Product Description
White Fused Alumina (white corundum) are produced by the grinding & classification of selected Macro grain feed stock in an advanced milling and classifying facility. This ensures an iron free product of narrow particle size distribution and high whiteness.
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.
