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.
