Brown aluminium oxide

Brown aluminium oxide micro powder

Brown Fused Aluminum Oxide Powder Brown fused alumina, with its mainly chemical composition AL2O3: 95%min, high melting point 2200 degree centigrade, it is widely used for abrasive media, refractory media and additives.


Brown Fused Aluminum Oxide Powder

It has several names in different countries: brown fused alumina, brown artificial corundum, brown aluminum oxide, brown fused Al2O3.

For the mainly chemical composition AL2O3 is about 95% or higher, it is often named brown Al2O3 powder. 

It is the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, and lapping and polishing processes, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important. It is offered in macro and micro powder form, in both P and FEPA grades.

 

It has brown color, gray color, coffee color, dark brown color, these different color is normally in fact. With high hardness (Mohs hardness: 9.0), high melting point (2200 degree centigrade), it has very stable chemical characteristic, high temperature resistance characteristic and super abrasion advantage.

The powder and grit are widely used for making abrasive such as grinding wheel, cutting discs, cut off wheel, sand stones, sanding belt, abrasive cloth. It is also widely used for different grade media, blasting media on stones, iron, wood and different metals for surface treatment.  For other usage, it is also commonly seen, such as for refractory media, abrasion additive, for making road, airway, ship decks, hardware instrument etc.
