Brown aluminum oxide is a generally used material in manufacturing abrasive products and refractory products. It is not so hard as WA grain. The products made from brown fused alumina is very suitable for tough task like large sandblasting outdoor, rough grinding work, etc. Meanwhile, it is a very moderately cost-efficient material comparing with WA.

Brown fused alumina application：
1) Abrasive: Produce ceramic grind wheel, resinoid grinding wheel, Grinding stone, Grinding block, sand paper, sand cloth, sand belt, polish wax,etc..
2) Refractory material: Mainly used for abrasion and high temperature resistance,in oxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc.
3) Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, de rusting, prevent corrosion, remove oxide skin etc.
4) Abrasion resistance.
5) Precision casting: Investmground: Mainly used for non-slip of airport and road, chemical factoryboard paving.ent casting technics of stainless steel and aluminum casting in coating.
