High purity White fused alumina WFA grit
High purity White fused alumina WFA grit was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.White corindon is white with the main crystal phase alpha-Al2O3.The White corindon 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.

Purpose:
1.Bonded abrasives and Coated abrasives
2.Floor/Wall Laminates
