History of Tungsten Carbide

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.
