Tungsten carbide powder
(WC) is the main raw material for the production of cemented carbide, chemical formula is WC
. Tungsten carbide powder is a black six square crystal, with metallic luster. Its hardness was similar to diamond, a good conductor of electricity and heat. The melting point is 2870 DEG, the boiling point is at a temperature of 6000 DEG , and the relative density is about 15.63 (18 DEG C). Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, soluble in mixed acid of nitric acid and hydrofluoric acid. The pure tungsten carbide
is fragile, but the brittleness will reduce, if mixed with a small amount of titanium, cobalt and other metals. Processing as the tungsten carbide cutting tool, in order to improve the anti explosion capacity, titanium carbide
, tantalum carbide
is often added. Chemical stability of tungsten carbide.
Tungsten carbide’s most outstanding property is its hardness. It is primarily used in the production of a wide variety of industrial tools and wear parts that are subject to a great deal of stress. Many high performance processes, such as metal drilling, turning and milling, are only possible with the industrial application of tungsten carbide in carbide tools.
