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.
