Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide, chemical formula WC. The full name is Wolfram Carbide. Tungsten carbide powder is a black hexagonal crystal with metallic luster, hardness similar to diamond, and 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 easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile. If it is mixed with a small amount of titanium, cobalt and other metals, it can reduce brittleness. Tungsten carbide, which is used as a cutting tool for steel, is often added with titanium carbide, tantalum carbide, or a mixture thereof to improve the explosion resistance. Tungsten carbide is chemically stable. Properties of tungsten carbide powder Tungsten carbide powder is a dark gray powder, which can b...
