Product Description

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


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.
