History of Tungsten Carbide

Tungsten carbide was first used in the 1920s when a German light-bulb company sought ways to make cheaper wiring for the light bulbs. Since tungsten carbide has a high melting point, this compound worked perfectly for light bulbs because the temperatures inside them get very hot. The production of tungsten carbide was perfected by the 1930s and other elements were also added in order to make the compound useful for other applications.
