It is common sense that there are many materials out there be famous for establishing trademarks of beauty and affluence. Gold and silver are popular example which have been used in jewelry since the Egyptians were building pyramids in 4000B.C., and copper’s been around since even before that! These metals have historically been signs of elegance and grace, and their reputations are well earned. So why not just follow the trends of history? Why not go with something new? Why not choose tungsten for your ring, locket, or bracelet?
As Bob Dylan so famously puts it, “The times they are a changin’. ” We’re living in the twenty-first century, and it’s time to embrace the new materials that scientists and engineers have spent so long hoarding for less aesthetic purposes. Tungsten is the hardest, most durable metal on earth. Unlike gold and silver, which are easily tarnished and lose their luster through the years, a piece of tungsten jewelry will never be parted from its shine. It’s an industrial metal designed for the heaviest tasks redesigned with beauty and charm in mind. Simply put, a tungsten ring is forever.
And that’s a great thing. If you’re going to put the time and effort in choosing the perfect piece of jewelry for a special occasion, why would you go for anything less than forever? Your jewelry should be like your memories - there’s no reason to ever let them fade. With a tungsten ring that’s one thing you never need to worry about. Take a hammer to a tungsten ring and it’s the hammer that’ll be sorry - not that any of the experts recommends that you do this, of course.
With a well selected tungsten ring you get all of the good from classic metals with even more features. You get the luster of a polished silver or titanium without the need to ever worry about regular maintenance. You get the elegance of gold but a hardness much closer to diamond. A piece of tungsten jewelry can withstand the test of time and be with you for the rest of your life.
Tungsten rings and jewelry are perfect for a variety of occasions and purposes. Whether chosen as a wedding ring or for a sign of lasting friendship, tungsten rings are a modern answer to the age-old search for elegance and grace and it is always the best choice. A tungsten ring can be thought of as a solid investment into your future.

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.

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.

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

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.

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.
