Tungsten Carbide Powder
Description of Tungsten Carbide Powder:
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.
Applications of Tungsten Carbide Powder:
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.
Specifications of Tungsten Carbide Powder:
Tungsten carbide is a high performance material formed from tungsten and carbon. AEM provides a wide range of tungsten carbides, from very fine grades with an average grain size of approx. 0.5 µm to very large average grain sizes of approx. 50 µm

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