Tungsten Carbide Button Quality Control

Tungsten carbide button quality control can be devided into inner quality control and external quality control. Inner quality control includes ingredient and construction. External quality control includes size and surface roughness.

Tungsten carbide button ingredient and construction are being designed by application requirement. The main ingredients are tungsten and cobalt. Its property is adjusted by the content of cobalt and grain size of tungsten carbide. If the requirement for tungsten carbide button is high toughness and hardness, then the content of cobalt is higher and grain size of tungsten carbide is bigger. If the requirement for tungsten carbide button is high wear resistance, then cobalt content is lower and grain size of tungsten carbide is smaller. After the ingredients of tungsten carbide button is confirmed, the property and life expectancy of tungsten carbide button is determined by its construction. Tungsten carbide button construction includes ingredients of tungsten carbide, cobalt content, grain size of tungsten carbide, thickness of cobalt layer.
