Tungsten Carbide (WC) is an extremely hard material with a high melting point that can be pressed and formed into shapes for use in cutting tools, abrasives, armour-piercing rounds and industrial machine parts. In many applications it is used a matrix with a cobalt binder.
Tungsten Carbide is around twice as stiff as steel with a Young's modulus of over 500 GPa and a low electrical resistivity of around 0.2 mW.m. In terms of hardness it is comparable to Sapphire or Ruby, ranking 9 on Mohs scale and requires cubic boron nitride or diamond tools and abrasives to be ground and polished into finished components.
Tungsten Carbide applications:
- Cutting tool inserts
- Armour-piercing rounds
- Industrial machine parts
