hardness of calcium carbide

Hardness varies but all cemented carbides are harder than the hardest metals. Tungsten carbide with a Vickers number of (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.
