brown fused alumina/brown corundum sand al2o3
Introduction
It is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200°c, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc.It has the features of high hardness and good strength, good self-sharpening, good thermal resistance, good thermal stability and chemical stability .
Applications
for Free grinding, such as glass industry.
for Friction products and abrasion resistance ground
for Resin bonded abrasive and coated abrasive products .
for Refractory material, Wear-resistant and fire-proof products.
for Grinding stone, Grinding block, sand paper, sand cloth, sand belt
for Coated abrasives sandpaper and Sandblasting/ Wet and dry blasting
for Producing mold of precision casting and Grinding, lapping and polishing media
