Tungsten carbide powder

Tungsten carbide powder: the annual production capacity is 2500 tons, and it is produced according to the national standard FWC standard. The production particle size range is 0.6-45 microns. It can also be produced according to customer requirements.
This product occupies 9.5% of the domestic market, ranking the 4th in China.
Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide, chemical formula WC. The full name is. Tungsten carbide powder is a black hexagonal crystal with metallic luster. Its hardness is similar to that of diamond. It is a good conductor of electricity and heat. The melting point is 2870 ℃, the boiling point is 6000 ℃, and the relative density is 15.63 (18 ℃). Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but soluble in nitric acid hydrofluoric acid mixed acid. Pure tungsten carbide is fragile. If a small amount of titanium, cobalt and other metals are added, brittleness can be reduced. Tungsten carbide, which is used as a steel cutting tool, is often added with titanium carbide, tantalum carbide or their mixtures to improve the antiknock ability. The chemical properties of tungsten carbide are stable.
