Grinding ball
Zirconia BallsIn certain applications Zirconia balls operate two to three times longer than metal or carbide.
Zirconia balls are inert to corrosive materials with the exception of hydrofluoric acid and hot,
concentrated sulfuric acid. Zirconia has a maximum useful temperature of 1800° F.
