Product Description
White fused alumina 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.
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.
