The chemical formula of tungsten carbide powder is WC. It is a good electric conductor with stable chemical properties. It is suitable for machining at high temperature and is the main raw material for the production of cemented Carbide.
Characteristic
Tungsten carbide powder is a black hexagonal crystal, with metallic luster, similar hardness to diamond, good conductor for electricity and heat. Melting point is 2870 ℃, the boiling point is 6000 ℃, the relative density is 15.63 (18 ℃).
The chemical properties of tungsten carbide powder are stable, insoluble in water, hydrochloric acid and sulfuric acid. It is readily soluble in the mixture of nitric acid - hydrofluoric acid. Pure tungsten carbide is brittle and can be reduced by adding a small amount of titanium, cobalt and other metals.
Applications
Tungsten carbide powder is suitable for machining at high temperature. It can make cutting tools, structural materials of kiln, jet engine, gas turbine, nozzle and so on.
