Tungsten Carbide Button Grain Size

According to different applications, tungsten carbide button producing requires middle or macro tungsten carbide grain size.

Tungsten carbide grain size affects tungsten carbide button properties from the following aspects:

1.Wear resistance and hardness. Tungsten carbide button hardness is related to cobalt content and tungsten carbide grain size. With the increase of cobalt content and tungsten carbide grain size, tungsten carbide button wear resistance and hardness decrease. The finer the tungsten carbide grain size, the better the wear resistance.

2.Bending strength. If the tungsten carbide grain size is 2um, bending strength arises with cobalt content. If tungsten carbide grain size is between 3um-5um, bending strength arises at the beginning along with cobalt content.

3,Fracture toughness. For the tungsten carbide button with the same cobalt content, if the tungsten carbide grain size is larger, then the fracture toughness is higher. On the contrary the smaller the tungsten grain size is, the lower the fracture toughness will be.
