White Fused alumina grain is one of the most commonly used abrasive grains for abrasive blasting, abrasive tools. It is an artificial abrasive material made from high purity Fused aluminum oxide blocks. WFA grain features including high hardness, roughness, and aggressive grinding ability.
White fused alumina blocks are melted in arc-furnace at 2250 centigrade for more than 24 hours and cool for about 20 hours. So it melted thoroughly and get very pure alumina crystals. The sieving process is automatically controlled after milling in ceramic ball milling equipment.
HAIXU WFA grain is made according to the FEPA standard to get specific particle distribution. The grain size of white fused alumina covered from F8 to F220.
