High Cleanliness Brown Aluminium Oxide Artifical Corundum F12-F220 for Bonded Abrasives
1. Product Description of Brown Aluminium Oxide
Brown Aluminium oxide is one kind of artifical corundum, it has brown color, so it is also named as
brown fused alumina(BFA),it is obtained from bauxite,coke, iron scrap through an electric arc furnace
process.
Brown Aluminium Oxide is widely used in bonded abrasives due to its characteristic of high hardness,
good self-sharpness and high toughness etc.

3. Main Products Features:
High hardness and toughness
Brown aluminium oxide contains more than 95% Al2O3,and its special crystal form make it an hard
and tough material,which offers stronger cutting force ;
Good Self-sharpness
Its block and sharp grit shape offers new sharp edge in the cutting process,it is suitable to cut the
alloy steel and stainless steel products.
4. Main Application of Brown Aluminium Oxide to make Bonded Abrasives
- Making resin bonded abrasives such as resin cutting discs to cut the alloy steel and stainless steel etc.
- Making ceramic grinding wheels for rough grinding, semi-finishing,fine grinding,grooving,cutting purpose.
In addition, Brown Aluminium Oxide is also widely used for making coated abrasives,refractory materials,
anti-skid materials, blasting media, brake pad etc.
