Browu fused alumina Introduction 

 Brown fused alumina is made by high qualitybauxite as main material, fusing and purifying in 

a pouring electricarc at a temperature of over 2200c, and made into different grain size through 

crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc.

Brown fused alumina Applications

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

3) Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, de rusting, prevent   corrosion, remove oxide skin etc..

4) Abrasion resistance ground: Mainly used for non-slip of airport and road, chemical factoryboard paving.

5) Precision casting: Investment casting technics of stainless steel and aluminum casting in coating.
