Tungsten metal has the highest melting point and the lowest vapour pressure of all metals. Tungsten metal has a very high density and low coefficient of thermal expansion. Tungsten metal powder is used as a raw material for the production of sintered tungsten and tungsten alloys.
Tungsten Carbide has extremely high hardness, high modulus of elasticity, and high thermal conductivity. This powder is typically used as a raw material that is critical for alloy properties.
