Carbide ball

• • • • • • • 
              Cemented carbide possesses high hardness, high rigidity, high strength, high temperature resistance, corrosion resistance, anti-oxidation and other good properties. It is widely used in modern tool materials, wear resistant materials, high temperature resistant materials, anti-corrosion materials and other aspects. The cemented carbide ball is mainly used as valve in petrochemical, the special bearing ball, the bearing ball of probe of testing instrument, electric tools, and bearing ball for mould.
