White Fused Alumina Fine Powder
Product Induction：
Our White Fused Alumina is electrically fused in arc furnace under the high temperature of above 2000℃ with high grade processed alumina as raw material. It is divided into a variety of particle sizes after crushing, shaping, magnetic separation and iron removing. The WA is dense texture, the hardness is slightly higher than that of Brown Fused Alumina, with high purity, good self-sharpness, strong grinding force, low calorific value, high efficiency, and acid and alkali corrosion resistance, good temperature stability, etc. White corundum abrasives are widely used in refractory materials, ceramic abrasive tools, resin abrasive tools, coated abrasive tools, grinding and polishing, sand blasting, precision casting and other fields.
Specification：
F280 F320 F400 F600 F800 F1000 F1200 F1500
Advantages：
The white corundum produced by our company has the advantages of high purity, strong self-sharpening, strong grinding force, high efficiency, high temperature resistance and corrosion stability. Abrasive tools made of it have the advantages of sharp grinding, low heat generation rate, high grinding efficiency, and little adhesion during use.
Application：
It is suitable for super-precision grinding and polishing in the crystal and electronics industries, as well as advanced refractory materials.
