Aluminum Oxide (Al2O3)

Alumina Oxide Ceramic Balls

Precision Plastic Ball Company offers a selection of aluminum oxide ceramic balls in a range of sizes for a variety of uses and applications. We are proud to be an industry-leading alumina ceramic ball manufacturer and supplier. Our inventory includes high-quality alumina oxide balls as well as chrome steel, stainless steel, aluminum, and plastic precision balls.

Features / Properties of Alumina Oxide Balls

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.
