White fused alumina is a kind of white abrasive made of high-quality aluminum oxide powder as raw material, refined and crystallized by electrofusion. The hardness is slightly higher than that of brown corundum, with slightly lower toughness, high purity, strong grinding ability, high efficiency, high temperature resistance and good thermal stability. After smelting and cooling at a high temperature of more than 2000 degrees, grinding and forming, and magnetic separation to remove iron, the white fused alumina can be sieved into various particle sizes.
Micropowder-grade white fused alumina is pickled, making the blasting procedure simple and easy to use, suitable for wet blasting and grinding.

1. White fused alumina can be used for surface decontamination and rust removal. It is suitable for all kinds of high-end products, handicrafts or hardware products, etc., to remove metal oxide layer, carbide black skin, dirt and rust on metal or non-metal surfaces.
2. White fused alumina can be used in a variety of sandblasting and grinding operations. After sandblasting, the surface is white and free of any magazines, eliminating the trouble of cleaning.
3. White fused alumina can be used for beautifying processing of products. It is suitable for matte or matte processing of various precious metal products, matte processing of crystal, glass, corrugated, acrylic and other non-metallic surfaces, and can make the surface of processed objects metallic luster.
4. White fused alumina can be used as an additive for various products. Additives for advanced refractories and other ceramic products.
5. White fused alumina is suitable for precision casting (special corundum for precision manufacturing). Abrasives made of white corundum, suitable for rubber tires, high-speed steel, etc., fine-grained sand can also be used in precision casting.
