Product Introduction of white corindon Polishing powder F220
WFA Abrasive blasting media is made of 99% aluminum oxide powder as raw material, which is refined and crystallized by electric melting (thus white corundum is also called fused alumina and white fused alumina). The white corundum sand produced by our factory has high purity, low impurities, low sodium content, uniform particles and high whiteness.

Characteristics of white fused corundum:
1. Because the white fused alumina has good self-sharpening, strong toughness, strong grinding ability, hardness higher than brown corundum, and low heat generation, it can not only be used as a raw material for abrasive tools such as cutting discs and grinding wheels.
2. White fused corundum can also be directly used in grinding and polishing, surface treatment, sandblasting and rust removal, and can be used in dry and wet sandblasting, surface polishing and polishing, and surface treatment before spraying.
3. Fused alumina sand has strong wear resistance, so it is suitable as an additive material for wear-resistant products.
4. White fused corundum has high refractory temperature, acid and alkali corrosion resistance, and good thermal performance. It can be used as high temperature resistant materials such as casting surface sand, thermally conductive ceramics, and high temperature resistant glue. It is widely used in casting, steel refractory, chemical refractory, 95 batteries, decorative porcelain and other special ceramics and porcelain for daily life, as well as high-tech industries such as semiconductors and electronics.
