Strong Cutting Force White Aluminum Oxide Fused Alumina Powder F230-F1200 for Polishing
1. Product Description of White Aluminum Oxide Fused Alumina Powder
White Aluminum Oxide is obtained from the fusion of industrial alumina powder in an electric arc furnace.
It has wide application in various applicaitions:
Grain Size F12-F220 is used for bonded abrasives or sandblasting purpose.
Grain Size F230-F1200 is used for ultra-fine grinding,polishing,lapping purpose.
Grain Size P12-P220 is applied for coated abrasives.
Section sand 8-5mm, 5-3mm, 3-1mm, 1-0mm is used for making high grade refractories.
