Brown Fused Alumina Oxide， also named corundum.
Mohs hardness 9.0 and such tough material with high strength, makes brown fused aluminium oxide as a necessary and superb raw materials for applications in abrasive industry.
There are two status with F Grit and P Grit Such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding, and abrasive discs, rolls, belts and pads.
Well performance of thermal shock resistance makes brown fused alumina oxide an important and fabulous raw material for refractory industries as well. Refractory bricks, castable refractories, ramming mass, gunning mix etc.
