Introduction of cemented carbide balls

Cemented carbide balls are high-temperature sintered alloy materials composed of refractory metal WC and cementing metal Co or Ni. Its alloy has high hardness and good wear resistance. It has good rigidity at room temperature, no obvious plastic deformation, and a small thermal expansion coefficient. The product has good dimensional stability and high processing accuracy. WC-Ni based alloy has good chemical stability and is resistant to acid and alkali corrosion, thereby increasing the service life of the product. Due to the above characteristics of cemented carbide, it is widely used in ball rolling elements in the bearing industry, rotating balls for fluid sealing, pump valve cores, oil excavation machine one-way valve cores, valve seats and many other high-tech fields of military and civilian products.
