Description
White fused alumina micro powder 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 and high whiteness.
It is white and harder and more brittle than White Fused Alumina. It features strong cutting force and steady chemical property and excellent insulation.
Application
It can be used for making bonded and coated abrasive tools, wet or dry blasting. It is also suitable for superprecision grinding and polishing of crystal and electronic industry and making high quality refractory materials. It can be adopted for the grinding of the hard and strong bending strength materials such as chilled steel, alloy steel, high-speed steel and high carbon steel. Meanwhile, it can be used as catalyst carrier, insulator and precisions founding sand, etc.
