Ferrous Free White Aluminium Oxide Fused Alumina F12-F220 for Blasting Large Work pieces
1. Product Description of White Aluminium Oxide Fused Alumina
WhiteAluminium Oxide is also known as White Fused Alumina,It belongs to the family of Electro-Corundum,
It is obtained by the industrial alumina powder,smelting in the electric furnace under high temperature.

3. Why White Aluminium Oxide is one ideal blasting media?
Firstly,it has the characteristics of angular shape,high purity of AL2O3,then offers higher hardness and
aggressive force in the blasting process.
Secondly, its white color gives no color contamination and ferrous pollution to the treated workpieces.
Thirdly,aluminium oxide white could be recycled for several times in the blasting process,then it is
One economical abrasives.
Fourthly,no hidden silicosis danger to the operator.
Therefore,white aluminium oxide is one ideal blasting media where requires minium ferrous contamination.
4. Main Application of White Aluminium Oxide in Blasting Applications:
White Aluminium Oxide is widely used for blasting media to clean the dust of large work pieces such as oil tanks,
chemical tanks, hulls, copper hooks, tin houses, containers, automotive industry; also for Paint removal,automatically
matte treatment for large glasses.
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.
