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.
