Description:
Brown Fused Alumina Micro Power is 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 with a high repeatability.
It is brown and features toughness and impact strength. It can bear high pressure.
Application
It is suitable for making bonded and coated abrasive tools, wet or dry blasting, superprecision grinding and polishing, making high quality refractory materials, grinding carbon steel, alloy steel, malleable cast iron, hard bronze and semi-conductor materials.
