White corundum is made from fine alumina oxide powder and crystallized by high temperature electric melting. Its hardness is slightly higher than that of brown corundum with low toughness, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, resistance to acid and alkali corrosion and high temperature thermal stability.

Advantage
- Does not affect the color of the workpiece
- Sandblasting can be used in the process where iron powder residue is strictly prohibited
- Micro powder grade is very suitable for wet sand blasting and polishing
- Fast processing speed and high quality
- The amount of iron oxide contained is extremely low, which is suitable for sand blasting operations where iron residues are strictly prohibited
