About Tungsten carbide

Tungsten carbide is a compound with equal compositions of tungsten and carbon. The compound finds specific use in various industrial applications owing to its high strength and resistance to corrosion. In fact, there are only a limited few materials on earth that can compare in strength with tungsten carbide. That said, tungsten carbide is available in varying grades which are chosen depending on the application. The grades vary in terms of grain size, hardness factors, and the use of a binder.

Tungsten carbide is also highly temperature resistant as well as corrosion resistant. In addition to the same, it can be molded into different shapes which make it extremely suitable for creating different dimension tungsten carbide valve seats for oil industries.
