White Fused Alumina for Refractory 0-1mm 1-3mm 3-5mm 5-8mm

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：

0-1mm 1-3mm 3-5mm 5-8mm 8-12mm

Advantages：

Application：

Weixiang White corundum Section sand is suitable for various uses, such as refractory materials.
