Product Details

High purity pink fused alumina/chrome corundum abrasive for polishing and grinding

Product Description

Pink fused alumina main material is bayer alumina, which is electrically fused in high temperature, being added with the right quantity of oxidized chromium. It is pink. Which are suitable for sandblasting,polishing and grinding.

Advantages

The processing of workpieces with pink fused alumina is not only fast processing but also high quality.

The use of pink fused alumina will not affect the color of the workpiece.

The content of Fe2O3 is very low, suitable for sandblasting operations where iron residues are strictly prohibited.
