Tungsten carbide is a compound of tungsten and carbon with the molecular formula WC, a black hexagonal crystal with a metallic luster and a hardness similar to that of diamond. It is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but soluble in a mixture of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile and can be made less brittle if small amounts of titanium, cobalt and other metals are added.
Purity: 99.9%
CAS: 12070-12-1
Widely used in high-speed cutting tools, kiln structural materials, jet engine components, metal ceramic materials, resistance heating elements, etc.
Used for manufacturing cutting tools, wear-resistant parts, copper, cobalt, bismuth and other metal melting crucibles, and wear-resistant semiconductor films.
Used as superhard tool material and wear-resistant material. It can form a solid solution with various carbides. WC TiC Co hard alloy cutting tools have been widely used. It can also be used as a modification additive for nbc-c hard alloys and a tac-c ternary system, which can reduce the sintering temperature while maintaining good performance. It can be used as an aerospace material.
