White aluminum oxide produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
Product Feature ：
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
