Product Details
High Self-sharpness White Aluminium Oxide Synthetic Corundum F12 -
F220 for Grinding wheels
1. Product Description of White Aluminium Oxide Synthetic Corundum
White Aluminium Oxide,also named as white synthetic corundum,WA, it
is made by industrial alumina powder,
electrically fused under high temperature more than 2000
degree,then crushed and screened into the different
grit size.

3. Why White Aluminium Oxide is Suitbale for making Bonded
Abrasives?
- Firstly,it has the characteristics of high purity of AL2O3,then offers
higher hardness andbetter grinding ability;
- Secondly, little heat generated in the surface of grinding wheel, which
offers good grinding effect.
- Thirdly, white aluminium oxide has ungular shape and higher
frangibility,its better self-sharpness make it easy
to provide new edges in the cutting or grinding process.
4. Main Application of White Aluminium Oxide in Bonded Abrasives
Applications:
White Aluminium Oxide has little higher hardness and slightly lower
toughness than that of Brown Aluminium Oxide,
that above products features makes it to be used for production of
bonded abrasive products for the grinding of the
steels with great hardness, such as high carbon steel, alloy steel,
and high speed steel etc.
In addition, it is also widely used in the following applications
of :
- Coated abrasives: abrasive belts, abrasive sheets etc.;
- Sandblasting Media;
- Grinding,polishing and lapping media;
- High grade refractories.
5. Package Details of White Aluminium Oxide:
- 25kg bag + Pallet;
- 25kg bag + Ton Bag;
- Ton Bag(Super Sack)
- Special packages can be customized.
