Alumina Oxide (Al2O3) Ceramic Balls

Alumina Oxide (Al2O3) Ceramic Balls are resistant to most corrive materials except for hydrochloric and hydroflouric acids or strong alkaline solutions. Alumina Oxide is non-porous, lighter than steel and, in ball form, harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable of spinning faster than steel balls.
