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.
