Product Description

We are  an aluminum oxide manufacturer specializing in brown fused aluminum oxide (Al2O3), otherwise known as brown fused alumina, through an electric arc furnace process. Our brown fused aluminum oxide is made into many shapes and grit sizes ranging from macrogrits to microgrits and powders. Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity.

Brown fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications. Our brown fused alumina grains and powders are available in standard grit and powder sizes and they can also be made to individual specifications. 

Bro

 brown fused aluminum oxide (Al2O3)ina


Brown fused alumina consists almost entirely of aluminium oxide and is almost iron-free. Brown fused alumina is less pure than white fused alumina. The special composition of this angular mineral makes it extremely stable. It is also both hard and tough. Brown fused alumina is primarily used as a blasting medium and in floorings. It belongs to the group of fused alumina.
