Tungsten carbide is what most tungsten rings are made of. It is incredibly durable but rather difficult to make. Tungsten carbide is a mixture of tungsten and carbon atoms within a structure formed by another metal, generally either cobalt or nickel. To form the metal tungsten powder, which is then mixed with the cobalt or nickel, you mix the carbon, tungsten and metal oxides and then heat until a bond is formed between the elements. After you mix the powder with the cobalt and add wax you mill the powder and then mold into the desired shape.

Tungsten rings come in a variety of designs. They're made of tungsten carbide generally and many feature gold overlays or diamond insets. Most are a silver that resembles platinum or white gold but you may also purchase black tungsten rings that may also feature overlays or designs. Tungsten rings are not expensive and may be purchased for as little as $50, as of the date of publication, although the black tungsten rings generally cost more than that.

Conclusion
Tungsten is an extremely durable and cost-efficient way to produce a variety of products. There is probably tungsten in some of the products around you right now. From televisions to race cars to wedding bands, tungsten may be found in many facets of our lives.

Tungsten-steel alloys are extremely hard and are made by combining tungsten and steel. They only require a small amount of tungsten compared to the amount of steel used. These alloys are used in many high speed applications such as rocket engine nozzles.

Tungsten is a resilient steel-gray metal, located in many different ores. While the metal was actually discovered by Carl Wilhelm Scheele in 1781, its many uses weren't discovered until the early decades of the twentieth century. Tungsten carbide has been used in mining and mechanical applications--everything from light-bulb filaments and x-ray tubes to drill bits.

Discovery
Scheele discovered a new acid which could be made from an ore called tungstenite--later known as scheelite. In 1783 Jose and Fausto Elhuyar managed to isolate and extract tungsten from the ore.

The Twenties and the Thirties
Tungsten carbide was used by the German company Osram in place of diamond drawing dies. Cemented carbide was invented and used for the cutting and milling of iron and steel.
