1, used in a large number of high-speed cutting tool, furnace structural materials, jet engine parts, metal ceramic materials, resistance heating elements and other products.

2. Used for manufacturing cutting tools, wear-resistant parts, melting crucibles of copper, cobalt, antimony and other metals, wear-resistant semiconductor films.

3. It is used as superhard tool material and wear-resistant material. It can form solid solution with many carbides. WC-TiC-Co carbide tool has been widely used. It can also be used as NbC-C and TaC-C ternary system. Carbide modified additives can not only reduce the sintering temperature, but also maintain excellent performance, can be used as aerospace materials.

4, using tungsten anhydride (WO3) and graphite in a reducing atmosphere 1400 ~ 1600 °C high temperature synthesis of tungsten carbide (WC) powder, and then by hot-press sintering or hot isostatic pressing sintering can be made of dense ceramic products.
