Product details

Black Fused Alumina/Black Corundum/Black Aluminum Oxide
Introduction

Black fused alumina is characterized by low Al2O3 and a certain amount of Fe2O3 (10% more or less) content, so it has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.

Application

It is mainly suitable for free grinding, such as coarse grinding before electroplating products, mainly for polishing and sandblasting of stainless steel, fabricated metal products, optical glass, bamboo products, and it is also new abrasive for manufacturing resin grinding wheels, cut-off wheels and emery cloth.

Property

The black fused alumina of the company concentrated basic tablets, with the characteristics of strong cutting power, high toughness, high flexibility, good abrasion resistance and high working efficiency, which is the best product for grinding and polishing, sandblasting stainless steel products.
