White fused alumina WA for coated abrasives

White fused alumina WA a highly pure form of aluminium oxide which is suitable for use with stainless steel and aluminium. This iron-free, reusable blasting medium is angular, brittle and hard. It has a powerful abrasive effect on the surface being blasted. White fused alumina belongs to the group of fused alumina.
