Alumina Oxide Ceramic Balls

Ceramic balls are particularly well suited for use in extremely harsh environments where high temperatures, corrosive and erosive substances are present.

Standard 99.5% alumina oxide ceramic balls have proven performance in wear, heat and corrosive environments, as well as, in maintaining dimensional stability at temperatures up to 20000 F.

Alumina resists oxidation and is tolerant to water, salt solutions, and many chemicals and acids, but is not suitable for use in hydrochloric or hydrofluoric acids or strong alkaline solutions.

Typical applications include pumps, valves and flow meters.
