Tungsten carbide with a Vickers nuer of 1700-2400 (85 HRC equivalent) is composed of 90% carbide particles by weight, 80% by volume. Most standard wear resistant alloys contain a maximum of 35% by volume of softer chromium carbide. We offer coating formulation options, mainly tungsten carbide (C1000, C1000Ni, C9000) and chromium carbide (C4000).

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 fabriion, a process developed in the 1920s is employed: the powdered tungsten carbide is mixed with another
Carbide flat blanks are commonly supplied in a C-2 material comprised of 94% tungsten carbide, 6% cobalt with an average grain size of 1.2 microns. Standard carbide round blanks are made of micrograin material with 90% tungsten carbide, 10% cobalt and .8 micron average grain size.
