White aluminium oxide in abrasives :
1. Description
White fused alumina is fused from high quality aluminium in high temperature. Its hardness is higher but toughness lower compared with brown aluminium oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding.
2. Specification
12#--80# 90#--150# 180#--240#
0-1mm 1-3mm 3-5mm 5-8mm 8-12mm
180#-0 200#-0 320#-0
3. Applications
White fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory materials.
4. Advantages
1) Not affecting the color of the processing cases.
2) Sandblasting in the non-iron process.
3) High speed processing.
4) Very low amount of iron oxide, suitable for non-ferrous blasting operations.
