Product Description

500-425um F40 White Aluminum Oxide Abrasive Grain-size Sandstone


1. Introduction

    White aluminum oxide is made from high purity Bayer process alumina. Raw materials and furnacing practices are carefully controlled to ensure the highest purity and optimum crystal structure. It is crushed in such a manner to produce blocky grain distributions with a higher bulk density.


    The hardness of white corundum is slightly higher than brown corundum, toughness is slightly lower, which has high purity, good self-sharpening, strong grinding ability, small heat, high efficiency, acid and alkali corrosion resistance, high temperature thermal stability.


2. Attribute

1.Chemical composition: 









2.Density: 3.95g/cm³

3.Hardness: 9.0 Mohs hardness

4.Grain size: 500-425um


3. Advantages

1. High purity; High stability

2. Competitive pricing

3. Lower risk of pollution

4. Better communication with customers



4. Applications

1. White Aluminum Oxide can be used as solid coated abrasive tools, wetting or dry sand blast. It can be used as super fine grinding, polishing and making high-grade refractory materials for crystal, electronic industry.


2. White corundum abrasives are mainly used in the grinding and polishing of metal parts, as well as in the manufacture of processing tools such as knives.
