PRECISION CERAMIC BALLS

Alumina Oxide (99.5% Al2O3)

Alumina oxide balls have proven capabilities with superior wear performance in corrosive environments and high temperature conditions.

The material resists oxidation and is tolerant to high moisture environments, salt solutions, and many chemicals.

Typical applications include pumps, valves and flow meters.
