Product Description

 

Alumina Oxide is a highly pure form of aluminium oxide.This iron-free, reusable blasting medium is angular, brittle and hard. It has a powerful abrasive effect on the surface being blasted.

Alumina powder is different formula after high temperature calcination. Alumina powder is difficult dissolved in water white amorphous powder, odorless, tasteless, strong chemical stability, high purity, true than significant, good insulation performance and so on

 

Advantages:
1. Does not affect the color of processed parts;
2. It can be used for sandblasting in a process where iron powder residue is strictly prohibited;
3. Plastic grade white corundum particles are very suitable for wet sandblasting and polishing and grinding operations.
