Alumina ceramics is a non-organic material with much higher hardness than metallic parts. Because of the universal existence of aluminum and oxygen, the price of alumina material maintain a comparatively lower price than other materials.

Alumina ceramic balls are mainly used as mechanical equipment components in bearings to increase their abrasion performance. By comparison with steel counterparts, alumina ceramics have properties of higher hardness, better roughness, better corrosion resistance and lower thermal expansion which make the bearings run longer time regardless of speed and temperature, and lubrication is also required less.
