Tungsten Carbide has a hardness close to diamond. This makes it a commonly used material for applications requiring high strength and wear resistance.

Other tungsten carbide properties include:high fracture strength, high thermal conductivity, high resistance to thermal creep, high electrical conductivity, high resistance to corrosion, high modulus of elasticity.

Tungsten carbide is harder than sapphire and retains a superior edge after extensive use.

It is not a metal alloy but the product of powder metallurgy; very fine grains of two materials are mixed and fused under high temperature and pressure.
