Alumina ceramic ball, at room temperature with high strength and high toughness, good wear resistance.

ceramic ball, at room temperature with high strength and high toughness, good wear resistance, high temperature corrosion resistance, high rigidity, not magnetic, electrical insulation. Zirconia ceramic ball at 600 °C, the strength, hardness is almost the same density as 6.00g/cm3, thermal expansion close to the metal if the expansion can be used with the metal bonding.
