Brief Introduction
Brown fused alumina is bauxite, coke, anthracite as main raw materials, use it made of abrasive, refractories. Brown fused alumina has high purity, high fluidity, low coefficient of linear expansion and corrosion resistance. It is far higher than the traditional brown corundum, which makes it the best aggregate and filling material for the refractory material of brown jade.
Application:
Mainly used in refractory materials, grinding wheel, sand blasting
1. Refractory materials .
2. Sandblasting - moderate hardness, high accumulation density, greater than major, toughness;
3. Free grinding -- free grinding in the fields of picture tube, optical glass, crystal glass and jade;
Package:
1. 1000KGS big bag
