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.
