Preparation of Tungsten Carbide Target

tungsten carbide target image

Tungsten carbide is a compound consisting of tungsten and carbon. It is a black six party crystal with metallic luster and hardness similar to diamond. It is a good conductor of electricity and heat. The tungsten carbide film is coated with a reinforcing phase on the tool, thereby improving the wear resistance, heat resistance and service life of the tool. Tungsten carbide target is the best choice for tool plating.
