Tungsten Carbide

       Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide, chemical formula WC. The full name is Wolfram Carbide, also translated as tungsten carbide, which is a black hexagonal crystal with metallic luster and a hardness similar to that of diamond. It is a good conductor of electricity and heat. The melting point is 2870°C, the boiling point is 6000°C, and the relative density is 15.63 (18°C). Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and is easily soluble in the mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is brittle, and if it is mixed with a small amount of titanium, cobalt and other metals, the brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or their mixture to improve the anti-knock ability. Tungsten carbide is chemically stable.



Origin China's main production enterprises are Zhuzhou, Zigong, Nanchang, Lushun cemented carbide factories. The tungsten carbide powder produced every year is mainly for domestic use, and some are exported to Japan, the United States, Germany, Italy, France, Sweden and other countries.
