Alumina oxide (AL2O3) is a top choice of ceramic balls due to its high corrosion resistance and high operating temperature capabilities. Precision alumina oxide balls are used where a material that resists abrasion, corrosion, and oxidation is required. Balls manufactured from alumina oxide typically are selected for high-temperature environments and high-wear applications due to their proven performance in extreme conditions. In fact, alumina oxide balls maintain dimensional stability up to 3180 ºF making them ideal for high-temperature environments. Our inventory of Alumina Oxide balls range in diameter sizes from .031 inches to 1".
Because of their durability, alumina oxide balls have a variety of heavy-duty and industrial uses. For example, the use of alumina oxide balls allows industrial bearings to run at higher speeds and higher temperatures.
