WFA 1),Purity 99% min; 2).Very low amount of iron oxide, suitable for non-ferrous blasting operations. 3).Competitive price.

White fused alumina for industrial abrasives.

White fused alumina, a kind of high-grade refractories, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

Advantages

1),Purity 99% min;

2).Very low amount of iron oxide, suitable for non-ferrous blasting operations.

3).Competitive and reasonable price.

Applications:

White Fused Alumina is designed for general industrial use in operations such as lapping, polishing, refractory coating for investment cast shells, decorative non-skid tile, and pressure blasting. It is used where a high purity and/or highly friable abrasive is desired.
