5/16 in. (0.3125) White Aluminum Oxide (Al2O3) Series Ceramic Precision Balls
Alumina Oxide (Al2O3) Ceramic Balls are resistant to the most corrosive materials except for hydrochloric and hydrofluoric acids or strong alkaline solutions. AL203 is non-porous, lighter than steel and, in ball form, harder than steel. They are virtually frictionless and are capable of spinning faster than steel balls.
