Brown fused alumina
It has some different names in different countries, such as brown aluminum oxide, brown fused AL2O3, brown corundum etc.
Ordered lumps, normal grit powder and grit are all workable in our company. Such as 0-1mm, 0-3mm, 0-5mm, 0-8mm,1-7mm etc.
Special size lumps need to order in advance, and normal stadard grit grit is normally produced.
Grit, grains. Its mainly chemical composition is Al2O3, about 95% more or less.
It seems brown, red brown, coffee, dark brown color. With its stable chemical, high hardness and high temperature resistance characteristic, it is suitable for high speed abrasion, sandblasting, rust cleaning, abrasive media and refractory materials.
For abrasive media, it is mainly used for making abrasive wheels, abrasive stones, grinding discs, cut off wheels, sand cloth, sand paper.
