The hardness of Tungsten Carbide is a function of its density, or how much of a material’s mass is contained in a unit volume. The SI unit for this property is kilograms per cubic meter, and the English unit is pounds per cubic foot. For a cubic inch of Tungsten Carbide, its density is 14.5 g\/cm3. And for different grades of tungsten carbide-cobalt alloy, the density can vary from 13-15g\/cm^3. And the hardness can go from HRA86 to HRA95 which is one of the hardest materials in the world, second only to diamond.<\/p>\r\n\r\n\r\n\r\n
