99% AL2O3 Fused Aluminium Oxide White Corundum F12 - F220 for Bonded Abrasives
1. Product Description of Fused Aluminium Oxide White Corundum
Fused aluminum oxide white is also called as white corundum,it is a high purity abrasive electrically fused
from the industrial alumina powder.
It has higher hardness and higher friability than the one of brown fused
aluminium oxide.

3. Main Product Features of Fused Aluminium Oxide (White Fused Alumina)
High Purity and High Hardness
The White Aluminium Oxide has high purity, which contains over 99.2% Al2O3 as well as dense crystal structure,
Its Mohs hardness is 9,which is little higher than the one of brown aluminium oxide, then it has better cutting or
grinding ability.
Good Self-sharpness
White Aluminium Oxide has ungular and sharp particle shape,the unique crystal structure also offers good self-sharpness
and high frangibility,it will provide new edges in the cutting or grinding process to achieve better effect.
4. Main Application of Fused Aluminium Oxide White Corundum in Bonded Abrasives
To make bonded abrasives such as resin cutting discs,ceramic grinding wheels for various purposes of surface grinding,
external and internal cylindrical grinding, creepfeed grinding of low or unalloyed steel, etc.
In addition, it is also widely used in the following applications of
Coated abrasives: abrasive belts, abrasive sheets etc.;
Blasting Media;
Grinding,polishing and lapping media;
High grade refractories.
