    Tungsten Carbide Powder

    Tungsten carbide powder (chemical formula WC) is the primary raw material for cemented carbide production. Tungsten carbide powder is a black six square crystal with a metallic luster. Its hardness is similar to diamond, a good conductor of electricity and heat. The melting point is 2870 C, the boiling point is at a temperature of 6000C, 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 is reduced if mixed with a small amount of titanium, cobalt, and other metals. Processing as the tungsten carbide cutting tool, titanium carbide, tantalum carbide is often added to improve the anti-explosion capacity.

    Tungsten Carbide Powder Applications

    Tungsten carbide’s most outstanding property is its hardness. It is primarily used to produce 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.

    Cast Tungsten Carbide Powder

    Cast tungsten carbide powder is a eutectic mixture of both tungsten carbides, W2C and WC, which has an exceptionally high degree of hardness and wear resistance. For this reason, it is primarily used in advanced wear protection and tooling technology.
