If you are looking for rings for engagement, then tungsten engagement rings are the best type of rings! It is a prior event to choose an engagement for the wedding but just as important that is why the tungsten engagement band makes for the perfect ring!
Before buying tungsten rings, you must be careful for selecting it. Because tungsten rings are so strong and durable, it can not be resized. A person should not take a guess on their ring size because if it turns out to be wrong there is nothing that can be done. A great idea would be to size your finger prior to purchasing the tungsten engagement bands. Most jewelers size a person’s finger with a sizer that appears to contain a bunch of rings on a keychain. This specific ring sizer is a non-comfort fit sizer and most tungsten engagement bands contain comfort fit. Most jewelers recommend a customer to purchase half a size smaller then what a person normally would. The reason this is recommended is because with a ring containing comfort fit the ring size is altered slightly.
When a person is purchasing a tungsten engagement ring a great idea would be to engrave the ring! Most people tend to believe the myth that the metal tungsten cannot be engraved, but that should be forgotten. All it takes for a tungsten engagement band to be engraved is either a laser or computer machine. Both of these machines get the job done and leave the ring shinny and smooth!
Tungsten engagement rings will be permanently polished and scratch proof! The metal tungsten will hold its shine for a lifetime! Tungsten engagement bands are the perfect type of rings for anyone because of their diversity. Tungsten engagement rings are available in many different styles and design such as the Celtic tungsten ring, Carbon fiber inlay tungsten rings, black tungsten rings, and many other designs!
When a person wants to remove a tungsten engagement band the first thing a person would want to do would be to try slipping the ring off of the finger. This could be done with soap or lotion, lubricating the finger can get it slippery enough to attempt sliding the ring off. If that does not work the vice grip tool can be used to crack the ring and eventually result in breaking the tungsten engagement ring off of the finger.
It would be a good idea to set a budget before going out to purchase a tungsten engagement band because tungsten engagement rings can range greatly in price. When a person finds the ideal tungsten engagement band, putting in enough time and energy will pay off in the end! It is important for a person to be patient and not settle for anything but the best!

The Size of Tungsten
http://www.tocoy.net
Tungsten jewelry is becoming popular and popular, although tungsten jewelry is very strong and durable, some problems are disappearing. For example, because of its durablity, it can not be resized again.
Tungsten rings crafted from tungsten carbide make excellent men’s wedding bands due to their incredible durability, beauty and affordability. Tungsten is a very hard and dense metal, mined from Wolframite or Wedding rings and bands created with tungsten carbide are very resistant to scratching and, therefore, are ideal for men who frequently work with their hands or perform heavy-duty work.
Because of tungsten’s amazing hardness, tungsten ring sizing is not possible. Some jewelers offer a lifetime guarantee that covers tungsten carbide ring sizing in case a new tungsten ring size is ever needed. The question “Can tungsten rings be sized?” is a common one. Tungsten simply is too difficult for any jeweler to work with and is virtually impossible to resize. The ring sizing process is suited for more malleable precious metals that offer pliability the jeweler can work with.
This is one reason why it’s important to know your proper ring size before ordering a tungsten carbide ring. Most tungsten rings for men are sized for a comfort fit, meaning that the traditional ring sizer found at most jewelry stores (which has a bunch of flat rings in various sizes on a large key ring) will not size properly for a comfort fit ring. Comfort fit rings are not flat on the inside. Rather, they are slightly round or domed, so that the ring fits more comfortably on the finger. These types of rings are particularly ideal for men or for individuals not accustomed to wearing rings. If you were sized with a non-comfort-fit or standard ring sizer, we recommend that you order a tungsten ring that is one half size smaller (i.e. if your standard ring size is 11, we recommend you opt for a 10.5 size). Another option is to visit a jewelry store and specifically ask to try on comfort-fit rings to determine your proper size.
Tungsten carbide ring sizing involves exchanging or replacing one size ring for another size ring, rather than a theoretical or hypothetical tungsten ring sizing process in which the ring would be altered by a professional jeweler. So if you are considering resizing tungsten ring or are in the market for a resize tungsten ring, check with the place where you purchased your ring to see if it’s covered by a guarantee or resizing policy to get a brand-new ring at no cost or a low cost.
According to my description, it is important to choose tungsten jewelry for you fingers. If you are pursueing comfort and fashion, then www.tocoy,net is a perfect choice. Any further questions please feel free to contact jeniffer@tocoy.net.

Protecting Your Tungsten Rings
http://www.tocoy.net
Eeven though Tungsten Rings are made of the strongest metal alloy on the planet, we should also care about and protect tungsten rings. However, though these virtually indestructible rings are designed to be almost maintenance-free, any ring or piece of jewelry worn as regularly in daily life as a wedding band is bound to accumulate a little bit of grime here and there, even a tungsten wedding band. Therefore, we can all benefit from learning some basic facts about the care, maintenance, and cleaning of Tungsten Rings.
Over time, dirt and oils from your skin and food, alcohols from cosmetics, and other substances with which you come into contact in your everyday routine can build up on any piece of jewelry worn without interruption and obscure the lifetime shine of tungsten wedding bands. A tungsten carbide band with no other alloy metal, or one that contains a nickel binder alloy, will not give you any trouble during cleaning as the chemical bond is impenetrable to oil.
All dirt and oils will stay on the surface of the ring and can be easily cleaned off by simply washing your tungsten wedding bands with hot, soapy water and wiping them with a soft cloth. Some jewelers carry tungsten wedding bands styles made with a cobalt alloy binder, a cheaper but inferior material. Use of cobalt binders is generally frowned upon by reputable jewelers because they are not as durable, cobalt causes severe adverse reactions in some wearers with allergies or sensitive skin, and cobalt leeches surface oils that can then never be removed and ruin the ring. Since NONE of the tungsten rings we carry contain cobalt, permanent discoloration and oil deposits will never be a problem. You may also find that during this simple cleaning process, marks that appeared to be scratches will disappear. These are not scratches at all; they are in fact other materials that formed weak bonds to your ring due to its unusual electrical properties.
Jewelry cleaning solutions, even those sold by high-end jewelry retailers or marketed as safe for all jewelry are not recommended as they may at worst contain enzymes and harsh chemicals that will permanently damage the luster or structurally weaken tungsten carbide rings, or at best are nothing but an overpriced variation on–you guessed it!– ordinary dish soap. It is also not recommended to place tungsten wedding bands in an ultrasonic cleaner; though the metal that makes up your ring is incredibly strong, tungsten carbide starts the forging process as two pure-element powders and can be badly damaged by exposure to ultrasonic waves. Don’t risk your precious ring or hard-earned money when the best solution is in your own kitchen!
As stated above, the best cleaning solution for a tungsten wedding band we can get it is the tried-and-true hot water and soap. After washing it, your tungsten rings will also like the new one.

Why Choose Tungsten Rings as Wedding Band?
http://www.tocoy.net
As we all know, tungsten is the second strong metal in the worl. So it is durable and strong as well as diamond and gold. Wedding is the results of love, and it is need a ring to satisfy the eternal love. While gold and diamond is so expensive, tungsten is strong and inexpensive. Moreover, tungsten has highest quality and reasonabe price which is the best choice to choose as wedding band.
Different places have different customs, especially for culture. Human culture is amazingly different and wildly diverse in a number of different ways. Yet, some customs such as marriage are shockingly universal. Consider the considerable geographic barriers, such as mountains, oceans and deserts that once separated mankind before advanced forms of transportation. However, marriage has somehow managed to permeate its way onto nearly every continent and culture. Likewise, some of the customs of marriage, such as the wedding ring, have also enjoyed a similar popularity.
Tradition states that wedding rings are exchanged at a wedding ceremony between couples. Wedding rings are usually worn on the fourth finger of the left hand. Why the left hand you might ask? This is a very good question without a precise answer. Logic would seem to dictate that wedding rings are worn on the left hand, due to the fact that approximately seventy-five percent of people are right handed. Many people have a tendency to want to keep their dominant hand free of objects, such as a right-handed person who wears a wristwatch on their left hand. While this is only a theory, it does seem to make a good deal of sense.
Nearly as old as wedding rings themselves is the practice of inscribing the rings with words of undying love. Of course, this can led to some awkwardness if the relationship ever ends, but the practice is still as popular as ever.
It is no coincidence that metals have consistently been used throughout history for wedding rings. Metals are durable, usually last longer than a human lifetime, and are generally pretty to look at. It is only during recent years, with the wide scale adoption of mechanization and tools, that the metal ring became comparatively easy to produce. Thus, in ancient times, a metal ring also was a work of art and would usually a valued possession.
The association between weddings and wedding rings across cultures is truly remarkable. So it is necessary to choose a good and beautiful style ring as the wedding band. It is also impressive to consider that the circle has been so consistently used, instead of another shape such as a necklace or a pin on one’s clothing. No doubt this is partially due to the inherent geometric appeal of the circle. Considering that the circle has no beginning and no end, it is perfect for use as a symbol for something that is eternal, such as love.

The Way to Avoid Fake Wathches
http://www.tocoy.netHow is a person supposed to know when a watch is worth what someone is charging for it, or if it is something that has no value at all. There are plenty of timepieces that are similar to the real ones but are know to be a cheap knockoff of the original. Unfortunately, there are lots of watches that try to make you think you are buying an expensive watch instead of a fake one. But there is another category of wristwatch products that include many expensive ladies watches being sold on the Internet and through magazine ads that are not actually counterfeit. The suppliers make the watch look identical from the exterior by including details such as the manufacturer’s logo, the serial number, and the exact design. With some of the counterfeit models looking identical, how can you avoid purchasing one?
The fake watches are not nearly as fine quality a product as the real ones are but are advertised in a deceptive way. The names that these timepieces use will sound similar to the luxury watches, but they are obviously not the same. Paying close attention to is when you are purchasing the watch. The market for fine timepieces is year round and there is no time of year where merchants are trying to get rid of them in a after Christmas sale or something similar. Some retail stores may attempt to sell counterfeit watches during these times with the hope that customers will buy thinking it is because of the sale. What might seem like a steal for you at the time is actually a steal for the seller.
Fake watches that are being sold do have a few things in common that a shopper can look for. To spot a fake timepiece, the buyer must look at things that are not as easy for someone to replicate. As mentioned above, some of the replicas are identical. Hand crafted, quality timepieces will not be sold for less than a couple hundred dollars unless they are fake. If you see someone with a sign that says its watches are seventy percent off, it is probably not real. No real luxury brands are ever sold at fire sales, massive inventory clearances or end of model year closeouts. If you see a brand sold mostly on auction sites, and never anywhere near it’s claimed retail price, it is not a luxury brand. Only in rare cases do these ultra-cheap imposter brands have official company websites that showcase the products. Just because you see a incredibly sophisticated website doesn’t ensure that the brand is actually a valid luxury brand.
The bottom line is that when a deal looks like a amazing and unbelievable opportunity, it usually should be avoided. The economics of the manufacturing and selling products make it impossible for new wristwatches to be sold at 70-95% off of a legitimate retail price.
Deceptive retail prices are used to get buyers excited that they are saving hundreds of dollars on an item. People get swept up by the idea that they are getting a steal of a deal and stop looking at the obvious clues that something is not right about the product they are buying.
You should take your time and look carefully at what you are considering purchasing. It is an unfortunate reality that people will sell the fakes. To make sure that you are not a victim, the best thing that can be done is to learn everything you can about a watch before you start checking with merchants to actually make a purchase.
Any further questions you can visit www.tocoy.net , you will find a good anwser.
The fake watches are not nearly as fine quality a product as the real ones are but are advertised in a deceptive way. The names that these timepieces use will sound similar to the luxury watches, but they are obviously not the same. Paying close attention to is when you are purchasing the watch. The market for fine timepieces is year round and there is no time of year where merchants are trying to get rid of them in a after Christmas sale or something similar. Some retail stores may attempt to sell counterfeit watches during these times with the hope that customers will buy thinking it is because of the sale. What might seem like a steal for you at the time is actually a steal for the seller.
Fake watches that are being sold do have a few things in common that a shopper can look for. To spot a fake timepiece, the buyer must look at things that are not as easy for someone to replicate. As mentioned above, some of the replicas are identical. Hand crafted, quality timepieces will not be sold for less than a couple hundred dollars unless they are fake. If you see someone with a sign that says its watches are seventy percent off, it is probably not real. No real luxury brands are ever sold at fire sales, massive inventory clearances or end of model year closeouts. If you see a brand sold mostly on auction sites, and never anywhere near it’s claimed retail price, it is not a luxury brand. Only in rare cases do these ultra-cheap imposter brands have official company websites that showcase the products. Just because you see a incredibly sophisticated website doesn’t ensure that the brand is actually a valid luxury brand.
The bottom line is that when a deal looks like a amazing and unbelievable opportunity, it usually should be avoided. The economics of the manufacturing and selling products make it impossible for new wristwatches to be sold at 70-95% off of a legitimate retail price.
Deceptive retail prices are used to get buyers excited that they are saving hundreds of dollars on an item. People get swept up by the idea that they are getting a steal of a deal and stop looking at the obvious clues that something is not right about the product they are buying.

Tungsten rings are famous for their durablity and scratchproof which are symbol of everlasting and eternal love. Tungsten rings will be the latest trend in contemporary world. If you are looking for fashion and comfort for your fingers as well as life, then tungsten rings are the best choice.
Factors for Paying Attention to Choose Tungsten Jewelry
Tungsten band is the symbol of eternal love can only be found in a ring with brilliant splendor. Tungsten rings are known as their timeless, durablity, sleek design, and unmatched strength against the brutal punishment of everyday wear.
Since that, when we search through the large available market for tungsten rings and other tungsten jewelry, it’s easy to get caught up in the glamor and forget to be cautious. Any web vendor you go to will make all the claims in the world that their stuff is best and that you have no need to worry, but are they telling the truth, or is it all an elaborate show to trick you into buying a sub-par piece? Here’s a list of 5 things I like to keep in mind when I go hunting for quality merchandise:
1. Pure Tungsten or Tungsten Carbide?
There’s a huge difference between a tungsten alloy ring and a tungsten carbide ring. How huge? If you’re expecting a hard as diamond tough as nails piece of jewelry, make sure it’s tungsten carbide. Tungsten alloys are softer and will scratch much more easily, meaning you’ll lose your polish much sooner. If you find yourself at a vendor that either doesn’t know the difference or won’t tell you, play it on the safe side and get out. There are lot’s of quality places out there who will.
2. Make Sure There’s No Cobalt
Cobalt is a common additive for many metal alloys, and there are plenty of manufacturer’s that try to cut corners by adding it to tungsten jewelry. In this case, that’s an extremely bad thing. If there’s any cobalt in the ring your skin will develop this greenish rash that will be very unsightly and really uncomfortable. That’s because cobalt will react with the oils in your skin. If the manufacturer isn’t upfront about their cobalt policy, hit the road and get yourself to someplace better at once!
3. The Problem With Nickel
Nickel is another common additive that people like to bring to the mix in order to reduce cost. Nickel isn’t nearly as bad as cobalt - it won’t react with your skin at all. However, it does weaken the tungsten a bit, meaning that your indestructible ring really isn’t so tough any more. Will it hold up to most stresses? Most likely yes. It is a risk I’d take when purchasing an item known for its lifelong endurance? Definitely not.
4. Know Your Ring Size
Because they’re so tough, tungsten rings are pretty impossible to resize in the same way that gold or silver jewelry is. Most websites and vendors will allow you to trade in your ring for a new one if your finger size changes, or if you guessed your partners’ size wrong, but don’t assume that this is the case. In addition, there’s generally a charge involved in getting a new one of the right size. Knowing your ring size before you go will save you a lot of grief.
5. It’s Pretty, But is it Permanent?
I tend to approach tungsten jewelry the same way that I’d approach a tattoo. Sure it may look good now, but is it something that I’d be happy with for the rest of my life? One of the strongest selling points of tungsten rings is its longevity. Don’t let some smooth talking salesperson talk you into a purchase you’re not 100% on board with.
After reading the article, you will find tungsten that you like it and the real tungsten. A tungsten ring can be one of the best, longest lasting purchases of your life. Bear these key factors in mind when searching around, and you’re sure to find a perfect solution to your jewelry needs.

Tungsten Copper
Tungsten is widespreading use in the world and copper is also putting use everywhere. Thus, tungsten copper is catching our eyes to make use of it.
Tungsten-Copper alloy is the composite of Tungsten and Copper, which owns the excellent performances of Tungsten and Copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. It is easy to be machined. It is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation.
Tungsten-copper composites are widely used in mechanical and electrical engineering. Typical applications include high-, medium-, and low-voltage circuit breakers, resistance welding electrodes, and electrode materials for electrical discharge machining, and heat sink materials for mocroelectronic packaging (W-Cu). More recently, W-Cu composites have been tested as heat flux components in experimental fusion reactors and as materials in MHD (magnetohydrodynamics) power generation systems.
Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten-copper (silver) composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.
Tungsten Copper for electrical
Tungsten copper electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Our tungsten-Copper materials are used owing to their unique physical properties.
Tungsten Copper for Heat Sinks
Tungsten-Copper high performance composites are fabricated from carefully controlled porous tungsten that is vacuum infiltrated with molten copper. This results in a W/Cu composite that has high conductivity and a matched low thermal expansion for heat sinks.
It is a composite of tungsten and copper. By controlling the content of tungsten, we can design its coefficient of thermal expansion (CTE), matching that of the materials, such as Ceramics (Al2O3, BeO), Semiconductors (Si), Kovar, etc.
Tungsten copper golf weight attachment
This refractory metal composite materials are a combination of tungsten combined with copper or silver. The manufacturing process is to press the refractory, sinter the pressed compact at a high temperature, and infiltrate with copper or silver. All this is done under very closely controlled conditions. The result is a relatively hard materials with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
Tungsten copper has the wide range of application , for example, for heat sinks. Therefore, if we take full advantage of it, we can be for the benefit of us.

Tungsten Wires
Tungsten is the most widespreading used as refractory metals. In wire form, it is essential for the production of lighting products and other goods where its high temperature properties are of use. Tungsten wires are including black tungsten wires,clean tungsten wires and tungsten rhenium wires and so on.
Black Tungsten Wires
The products are featured with minimum formation at high temperatures, high recrystallization temperatures, uniformity in dimension and excellent coil ability. For tungsten rod weighing 3kg/pc, its rough welding tungsten wire weighing 5kg/pc. Customers are allowed to choose various types of tungsten wire in accordance with their specific applications.
The important applications are for the production of coiled incandescent lamp filaments, cathode and support structures for power tubes, heating elements for high temperature furnaces and evaporation sources in metallizing processes. Thicker wire sizes, straightened, finish-ground and cut into rod pieces are widely used for glass-to-metal seal lead parts in the lighting and electronic industries.
Clean Tungsten Wires
Clean tungsten wires are the surface of electrolytic polished tungsten wire, they shall be smooth, clean, gray silver with metal luster. The tungsten wire features excellent formability, long life and super lighting efficiency. Mainly applied for making various electron tubes, H series auto lamp, halogen lamp and other special lamp.
Tungsten Rhenium Wires
Tungsten-rhenium wire doped with rhenium, which has much better ductility and stability than pure tungsten in high temperature.
To improve the quality of tungsten wire, it is always mixed some additives during sintering procession, such as Na2O, K2O, SiO2, ThO to enhance the capacity of high-temperature creep resistance and high temperature anti-sag of tungsten wire. In order to improve the tenacity of tungsten wire and prevent the deformation under high temperature, it usually added some oxides, such as silica, alumina, potassium and so on.
Once tungsten wire used at high temperature after recrystallization, it becomes quite fragile. And it can be easily broken under the condition of shaking and vibrating. In some electric light source products require high reliability, in order to prevent fragmentation of lamp filament, tungsten wire often doped 3 to 5% rhenium, known as the tungsten rhenium wire which can make the extension of tungsten-brittle transition temperature decreased to room temperature or below room temperature.
Tungsten wire has fiber structure, when the temperature reaches 1500-1600 ℃, the tungsten filament would turn, and cause high-temperature sag. All wires showed here are doped tungsten wires and manufactured by the high tech of doping, acid washing, isostatic pressing, PLC controlled direct sintering, swaging and auto feeding.

Tungsten
Although tungsten is more and more popular, people are also not familiar with it. Thus, I will give the detailed description about tungsten. At first, we will talk about the characteristics of the tungsten.Characteristics:
Tungsten is a very hard, dense, silvery-white, lustrous metal that tarnishes in air, forming a protective oxide coating. In powder form tungsten is gray in color.
The metal has the highest melting point of all metals, and at temperatures over 1650 oC also has the highest tensile strength. Pure tungsten is ductile, and tungsten wires, even of a very small diameter, have a very high tensile strength.
Tungsten is highly resistant to corrosion. It forms tungstic acid (H2WO4), or wolframic acid from the hydrated oxide (WO3) and its salts are called tungstates, or wolframates.
Tungsten is one of the five major refractory metals (metals with very high resistance to heat and wear). The other refactory metals are molybdenum, tantalum, rhenium and niobium. Uses:
Tungsten and its alloys are widely used for filaments in older style (not energy saving) electric bulbs and electronic tubes. It is used for making heavy metal alloys because of its hardness. Tungsten is used for high-temperature applications such as welding.
High speed steel (which can cut material at higher speeds than carbon steel), contains up to 18% tungsten.
Tungsten carbide (WC or W2C) is extremely hard and is used to make drills. It is also used for jewelry because of its hardness and wear resistance.
Discovered:
In 1779 Peter Woulfe deduced the existence of a new element - Tungsten - from his analysis of the mineral wolframite (an iron manganese tungstate mineral). Tungsten was isolated by Fausto and Juan Jose de Elhuyar in 1783 by reduction acidified wolframite with charcoal. The element name comes from the Swedish words 'tung sten', meaning heavy stone. The chemical symbol, W, comes from the original name of the element, Wolfram.
Harmful effects:Tungsten is considered to be of low toxicity.
Source:
Tungsten is not found free in nature. The principal ores of tungsten are wolframite (an iron manganese tungstate) and scheelite (calcium tungstate, CaWO3). Comercially, the metal is obtained by reducing tungsten oxide with hydrogen or carbon
Isotopes:
Tungsten has 33 isotopes whose half-lives are known with mass numbers from 158 to 190. Of these, three are stable: 180W, 182W, and 186W.
To sum up, we know the tungsten’s characteristics, uses, discovery, source and istopes. In my opinion, you may have a better understanding of tungsten.

How is Tungsten Wire Made?
In our daily life, the incandescent light are widespreading use. As we all know, the light must use the tungsten wire. However, do you know how the tungsten wire is made? The process of making tungsten wire is very complicated and difficult.The process must be tightly controlled so as to insure the proper chemistry as well as the proper physical properties of the finished wire.
If we have pure tungsten powder, how do we make wire?
Firstly, Pressing - Tungsten powder is sifted and mixed. A binder may be added. A fixed amount is weighed and loaded into a steel mold which is loaded into a press. The powder is compacted into a cohesive, yet fragile bar. The mold is taken apart and the bar removed.
Secondly, Presintering - The fragile bar is placed into a refractory metal boat and loaded into a furnace with a hydrogen atmosphere. The high temperature begins to consolidate the material together.
Thirdly, Full Sintering - Bar is loaded into a special water-cooled treating bottle. Electric current will be passed through the bar. The heat generated by this current will cause the bar to densify to about 85% to 95% of full density and to shrink by 15% or so. Additionally, tungsten crystals begin to form within the bar.
Besides, Swaging - The tungsten bar is now strong, but very brittle at room temperature. It can be made more malleable by raising its temperature to between 1200°C to 1500°C. At this temperature, the bar can be passed through a swager. Typically a swager will reduce the diameter about 12% per pass. Swaging elongates the crystals, creating a fibrous structure. Although this is desireable in the finished product for ductility and strength, at this point the rod must be strees-relieved by reheating. Swaging continues until rod is between .25 and .10 inches.
Last but not least, Drawing - Swaged wire of about .10 inches can now be drawn through dies to reduce the diameter. Wire is lubricated and drawn through dies of tungsten carbide or diamond. The exact reductions in diameter depend on the exact chemistry and the final use of the wire. As wire is drawn, fibers again elongate and tensile strength increases. At certain stages it may be necessary to aneal the wire to allow further processing. Wire can be drawn as fine as .0005 inches in diameter.
All in all, making tungsten wire is really complex. You must be careful for every step. Also, you must be very surprised a small bulbs unexpectedly also contains such complicated procedure.

Tungsten jewelry are the perfect for those who are going in for the cozy and prevlence. Because tungsten is durable and scratch proof, it is the excellent choice for marriage.
The History and Development of Tungsten
Nowadays, tungsten is becoming prevlent and fashionable, thus you must be curious about tungsten’s history and development. Tungsten has a long history and rapid development, I will give a detailed description as following.
In early time, tungsten (Swedish and Danish tungsten meaning "heavy stone", even if the current name for the element in Swedish is Wolfram) was first suggested to exist by Peter Woulfe in 1779 who examined wolframite and concluded that it must contain a new substance. In 1781 Carl Wilhelm Scheele ascertained that a new acid could be made from tungstenite. Scheele and Torbern Bergman suggested that it could be possible to obtain a new metal by reducing tungstic acid. In 1783 JosŽ and Fausto Elhuyar found an acid in wolframite that was identical to tungstic acid. In Spain later that year the brothers succeeded in isolating tungsten through reduction of this acid with charcoal. They are credited with the discovery of the element.
Tungsten is an element #74, like gold, silver and platinum, It is naturally occurring and is one of the main elements which are responsible for the development of human civilization. Without tungsten, we would not have the incandescent light bulb as the filament inside the bulb is tungsten and has the toughness and resilience exceeding any other metal. In 1922 the Germans developed Tungsten Carbide as the material used in making better cutting tool bits for precision milling and cutting of steel. In World War II, tungsten played an enormous role in background political dealings. Portugal, as the main European source of the element, was put under pressure from both sides, because of its sources of wolframite ore. The resistance to high temperatures, as well as the extreme strength of its alloys, made the metal into a very important raw material for the weaponry industry.
Now tungsten jewelry is in widespread use in the worldwide machinery of modern industry and is a darling super alloy that has made aerospace advances possible. And also it is still the one little item that makes a light bulb work.
From then to now, tungsten deep into people's lives and everywhere in the world. To a certain extent, we can not live without tungsten. According to the description, you may have a better understanding about the tungsten’s history and tungsten’s development.

What is Tungsten Properties ?
.jpg)
Nowadays, tungsten is becoming more and more popular, so people are curious of everything about tungsten. Today we will talk about the tungsten property and it will improve your knowledge.
Tungsten has unique properties that have made it the only material suitable for many applications. Tungsten has unusually high strength at very high temperatures.
Among metals, tungsten has the highest melting point and lowest coefficient of thermal expansion and lowest vapor pressure.
Other tungsten properties include high tensile strength ,high thermal conductivity, high resistance to thermal creep ,high electrical conductivity ,high resistance to corrosion and high modulus of elasticity
Pure tungsten, that is, before alloying with any other material, is steel-gray to tin-white and is a very hard element. Tungsten can be cut with a hacksaw when it is very pure (it is brittle and hard to work when impure) and is otherwise worked by forging, drawing, or extruding. This element has the highest melting point (3422 ¡C) (6192 ¡F), lowest vapor pressure and the highest tensile strength at temperatures above 1650 ¡C (3000 ¡F) of all metals. Its corrosion resistance is excellent and any attack by a mineral acid is virtually imperceptible. Tungsten metal forms a protective oxide when exposed to air but can be oxidized at high temperature. When alloyed in small quantities with steel, it greatly increases its hardness.
Tungsten is: Four times stiffer than steel Six times stiffer than aluminum 100 times stiffer than plastic
Tungsten has the highest melting point and boiling point of all the elements, melting at 3,420 degrees C or 6,700 degrees F, and boiling at 5,700 degrees C and 10,300 degrees F. What this means to the average person is that on the surface of the Sun, Tungsten would become liquid, but if you dropped a piece of Tungsten from outer space, it would enter the Earth’s atmosphere, heat up and glow to red color, and still hit the Earth in a solid piece. And Atomic Symbol is W (Wolfram)，Atomic Number is 74，Atomic Mass is 183.85，Melting Point is 3420 C，Boiling Point is 5800 C，Density is 19.25 g/cc，Structure is Body Centered Cubic.
To sum up, because of the tungsten’s durability and extremely resistent,tungsten Carbide has a hardness close to diamond. This makes it a commonly used material for applications requiring high strength and wear resistance.

The Manufacturing Process for Tungsten Jewelry
As we all know, tungsten jewelry is strong and durability, we will talk about the manufatureing process for tungsten jewelry as following:
Tungsten with carbon and other elements are ground into a powder and then compressed with high pressure dies to form a ring blank.
The blank is then fired in an oxygen free furnace at an astounding 6,200 degrees Fahrenheit. This process call edsintering creates the hardest metal used for making jewelry.
The ring is then cut and shaped using diamond tools with approximately 30 steps required for completion. The cutting and shaping of a tungsten ring is similar in many ways to the cutting and polishing of a rough diamond.
Tungsten rings inlaid with gold, silver, platinum or mokume gane are created by grinding a channel in the center of the ring and precisely "swedging" the metal into the channel under extreme pressure.
The ring is then skillfully polished with diamond polishing tools and wheels creating a permanent luster and polish not possible with other metals.
A Tungsten Carbide ring will remain polished forever, and is scratch resistant. It is a unique metal that epitomizes today's man more than any other.
A complete guide to the manufacturing process for cemented tungsten carbides is presented in this paper. Tungsten carbide is a compound formed by the reaction of tungsten metal powder and carbon powder at temperatures of 2,600-2,700°F. The paper lists various metals and compounds used in manufacturing of tungsten carbide, and describes the chemical process for tungsten ores, and the various factors that control the particle size of the tungsten metal powder. Chemical formulae from scheelite ore to tungsten carbide are included and the sequence of processes involved in the production of carbide grades are explained in detail.

China’s Demand for Tunsten Continues to Grow
The tungsten is the rare resources in the world, especially in the China. While the popolation of China is so large so that person has the less per capita. Because of it, Chinese government take some polocies to solve it!
In addition to previous quotas set to limit the export of tungsten, the Chinese government has again cut back on the production and shipment of minor metals such as tungsten, molybdenum and vanadium. According to the Ministry of Industry and Information, these metals represent a non-renewable resource that gives Chinese manufacturing an advantage, hence the need for these further restrictions.
Recent analysis suggests China’s existing tungsten resources will last just 20 years. The article states that China will account for 37% of global consumption this year. The specialty steel sector will be the second largest buyer of tungsten, accounting for 22% of China’s consumption, behind the local hard alloy sector, which takes 58% of all Chinese tungsten production.
China holds approximately 50% of the world’s known tungsten reserves and it has put a hold on development of new tungsten mines until after June 2011.
Improving the current, many scientists creat the new resources to satisfy the people’s demand.
Newcrest has announced it will begin drilling tenements alongside existing gold works in Western Australia, early in 2010, to determine the prospectivity for tungsten.
At the same time, Icon Resources announced to the market its successful fund raising to expand drilling and proceed with pre-feasibility at the existing Mt Carbine open-cast pit. This is perhaps the most exciting stage for patient investors to-date, as the resource potential beyond what is currently confirmed, is explored. If the seams continue into the hill and further underground than previously documented, Mt Carbine will be well-positioned to expedite the project as desired.
"Further supply from other Australian sources won't so much dampen our opportunities as support the premise of Australia becoming the dominant supplier of tungsten to world markets. Our sovereing risk, technological and productivity track-records make the country a reliable source of strategic metals," he said
Because the tungten is rare, it used to be the wedding band which represent for cherish each other!

Should I be concerned with Cobalt in my Ring?
Absolutely YES!
Many tungsten and tungsten carbide rings have Cobalt in them. The alloy containing Cobalt is easier to procure and rings containing Cobalt are commonly sold. However, rings containing Cobalt will develop a negative reaction to your skin. After a short period, the ring will develop oxidation spots that cannot be removed or polished out. This is due to the Cobalt reacting to the human body in which many people's skin can be irritated causing itching. You can easily prevent this from happening by purchasing one of our Cobalt-free, hypoallergenic, Tungsten Forever Carbide rings. As following, we will talk about the concept and compound of cobalt.
Cobalt (pronounced /ˈkəʊbɒlt/ KOH-balt)[3] is a hard, lustrous, gray metal, a chemical element with symbol Co and atomic number 27. Cobalt-based colors and pigments have been used since ancient times for jewelry and paints, and miners have long used the name kobold ore for some minerals.
Cobalt occurs in various metallic-lustered ores, for example cobaltite (CoAsS), but is mainly produced as a by-product of copper and nickel mining. The copper belt in the Democratic Republic of the Congo and Zambia yields most of the cobalt mined worldwide.
Cobalt is used in the preparation of magnetic, wear-resistant, and high-strength alloys. Smalte (cobalt silicate glass) and cobalt blue (cobalt(II) aluminate, CoAl2O4) gives a distinctive deep blue color to glass, ceramics, inks, paints, and varnishes. Cobalt-60 is a commercially important radioisotope, used as a tracer and in the production of gamma rays for industrial use.
Cobalt is an essential trace element for all animal organisms as the active center of coenzymes called cobalamins. These include vitamin B12 which is essential for mammals. Cobalt is also an active nutrient for bacteria, algae, and fungi.
Common oxidation states of cobalt include +2 and +3, although compounds with oxidation state +1 are also known. The most common oxidation state for simple compounds is +2; cobalt compounds in the +3 state are oxidizing agents. Cobalt(II) salts form the red-pink [Co(H2O)6]2+ complex in aqueous solution. Adding excess chloride will change the color from pink to blue, due to the formation of [CoCl4]2−.[2] the compound is harmful for our health.
According to my description, so you should be careful to choose the tungsten rings whether the rings has the cobalt in the future. It is helpful for your health and your life！
