White Fused Alumina is made of high-quality aluminum oxide powder as raw material and smelted by electric fusion. It has white color, high hardness, slightly lower toughness, high purity, excellent self-sharpening, strong grinding power, low heat generation, and high efficiency. , resistant to acid and alkali corrosion, high temperature resistance, good thermal stability, etc.
It is not only a high-grade abrasive material, but also a high-grade grinding and polishing material. The abrasives processed with it are suitable for grinding high-carbon materials. steel, high-speed steel and various stainless steels. It is also widely used in precision casting, steel refractory, chemical refractory, 95 electric porcelain, decorative porcelain and other special ceramics and daily life porcelain, as well as high-tech industries such as military industry and electronics.
Grit No.: JIS “240-JIS”6000 P12-P2500 F12-F1200.
