Tungsten carbide is a compound composed of tungsten and carbon, the molecular formula is WC, the molecular weight is 195.85. Black hexagonal crystal, metallic luster, hardness and diamond similar, for electricity, heat good conductor. Application 1.Used for manufacturing cutting tools, wear-resistant parts, melting crucible of copper, cobalt, bismuth and other metals, wear-resistant semiconductor film.
2.It is widely used as high speed cutting tool, kiln structure material, jet engine parts, cermet material, resistance heating element, etc., 3.Used as super hard tool material, wear resistant material. It can form a solid solution with many carbides. Wc-tic -Co carbide cutting tools have been widely used. It can also be used as a modified addition of carbides in NbC-C and TaC-C ternary system, which can not only reduce the sintering temperature, but also maintain good properties, and can be used as aerospace materials.
