99.2% Purity White Aluminium Oxide Artificial Corundum F12 - F220 For Surface Pretreatment
1. Product Description of White Aluminium Oxide Artificial Corundum
White Aluminium Oxide also called as white fused alumina(WA),which belongs to the group of electrical
corundum,it selects the industrial alumina powder as raw material by melting in electric arc furnace under
high temperature more than 2000 degrees.It contains at least 99% alpha-Al2O3.
It has the characteristics of dense texture,high hardness,high purity,good self-sharpness&grinding
ability,small heating power,high efficiency,acid and alkali corrosion resistance, high temperature
resistance and good thermal stability.

3. Product Process of White Aluminium Oxide Artificial Corundum
4.Main Features of White Aluminium Oxide Artificial Corundum
- High Purity,no foreign contamination to the treatment surface;
- Ferrous free,the ideal abrasive for application where ferrous contamination prohibited;
- High Hardness and sharp shape offers more aggressive force in blasting process.
5. Surface Pretreatment Application of White Aluminium Oxide Artificial Corundum
White Aluminium oxide is widely used as blasting media for surface pre-treatment to enhance the surface
adhesion such asTeflon, PU, rubber, plastic coating, rubber roller, electroplating, metal spray welding,
pre-titanium treatmen etc.
White fused alumina is also 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.
