WHITE
ALUMINUM
OXIDE

White Aluminum Oxide is a high purity media used in many medical and aerospace applications. Free of almost all iron content, "white" leaves a bright, clean finish in pressure and suction abrasive blast systems

White aluminum oxide is a friable, high purity, medium density, abrasive. It is designed for general industrial use in operations such as lapping, polishing, refractory coating for investment cast shells, decorative non-skid tile, and pressure blasting. It is used where a high purity and/or highly friable abrasive is desired.
