Product Description
White Aluminum Oxide Emery Powder F100-F220 F230-F1200 For Polishing & Lapping
1. Product Description of White Aluminum Oxide Emery Powder
White Fused Alumina is manufactured by the fusion of high grade industrial alumina powder in an electric arc
furnace at temperatures greater than 2000 degree through a slow solidification process,then crushed into
different grain size after magnetic separation.
It has high purity of 99.2% alumina and high whiteness,so it is named as white fused alumina.
It has the higher hardness than the one of brown aluminum oxide,then it is suitable for grinding high hardness
steel such as high speed steel, high carbon steel, alloy steel, etc.
