White fused alumina is very pure and extremely hard. Aluminum oxide is used to anchor pattern creation prior to coating or bonding, rust, scale removal, sweeping, matte surface finish of steel, stainless steel, aluminum, non-ferrous metals, glass, stone and other surfaces. It can be recycled and will not leave residues on the surface of the workpiece
