Product Description
White Fused Alumina Powder 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.
