The main component of tungsten carbide bearing balls is tungsten-cobalt alloy (WC-CO), tungsten carbide bearing balls made of special working conditions, with high temperature resistance, good wear resistance, as well as corrosion resistance and other excellent characteristics, and in the high vacuum antimagnetic tungsten carbide bearing balls and so on have achieved certain results.
Tungsten carbide fine grinding ball has the characteristics of high strength, high abrasion resistance, high precision, high temperature resistance, corrosion resistance, etc., which is widely used in the petroleum industry bearings and so on. As the hardness of cemented carbide ball material is up to HRA87 or above, which is more than twice the Rockwell hardness of steel ball, it is a difficult material to process.
