Product Description

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.
