White Fused Alumina for Abrasive

White fused alumina abrasive is suitable for surface beautification of various high-end products, crafts or hardware. After sandblasting, the surface is white without any impurities, eliminating the trouble of cleaning. White fused alumina fine powder can be used as the head of polishing and grinding. It can also be used as various product additives. It can be used for solid and coated abrasives, wet or dry or blasting sand, suitable for ultra-fine grinding and polishing in crystal and electronic industries, and for making advanced refractory materials. It is suitable for processing hardened steel, alloy steel, high speed steel, high carbon steel and other materials with hard hardness and high tensile strength.
