High purity 99.2% Aluminium Oxide Blasting Media White Fused
Alumina for Pretreatment
1. Product Description of White Aluminium Oxide Fused Alumina
White Fused Alumina is also called as synthetic aluminium
oxide(WA),it selects the industrial alumina
powder as the raw material,then fused in the electric arc
furnace,finally made into different grit size.
This white high purity abrasive is widely used in various
industries such as automotive,aviation,medical,
dental,cosmetic and flooring etc.

3. Why White Aluminium Oxide is one ideal blasting media?
White fused alumina contains at least 99.00% Al2O3, that high purity and white color offers no impurity contamination
to the treatment surface.
White fused alumina is more friable,then it will break down quickly
and expose new edges in its surface,which offers
new aggressive force in blasting process and more easily achieve
the blasting effect.
White fused alumina has high hardness and toughness,then it will be
reused several times in blasting process,then it
is an recyclable and economical abrasive.
- Minium Ferrous Contamination
White Aluminium Oxide offers minium ferrous contamination to the
treatment surface.
Therefore it is an ideal balsting media where ferrous contamination
forbidden.
4. Main Application of White Aluminium Oxide in Blasting
Applications:
- Surface cleaning for metal oxide scale, carbide black skin
- Sandblasting for metal or non-metal surface to remove the rust such
as gravity die casting mold,oxide scale or agent
removal from rubber molds
- Sandblasting the ceramic surface to remove the black spots etc.
- Glaze color removal and painting rebirth etc.
In addition, it is also widely used in the following applications
of :
- Bonded brasives such as resin cutting discs,grinding wheels etc.;
- Coated abrasives: abrasive belts, abrasive sheets etc.;
- Grinding,polishing and lapping media.
- High grade refractories.
5. Available Blasting Equipment of White Aluminium Oxide:
