Tungsten carbide | chemical compound | Britannica

Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the powdered tungsten carbide is mixed with another ...

Things to Consider When Selecting a Tungsten Carbide Material

Tungsten carbide as used here means WC grains in a cobalt binder. Cobalt is softer than the tungsten carbide grains so the more cobalt you have the softer the overall materials will be. This may or may not relate to how hard the individual grains are. Grain size and Cobalt in combination.
