White fused alumina, produced by alumina in the electric arc furnace with temperature more than 2200℃,after cooling,crushing and grinding,it was screened to different grits,and with round shape,it it applied for sandblasting and polishing industries,also,it can be used for abrasive tools,such as resin grinding wheel, ceramic grinding wheel, abrasives belt, abrasive paper and polishing.
Applications
a.) WFA Grinding wheel, cutting wheel, abrasive disc,
b.) Sandblasting, polishing
c.) Abrasive paper, abrasive belt
