Product Description

White corundum powder is white, harder and more brittle than brown corundum, has stronger cutting force, good chemical stability, and better insulation. It can be used as bonded and coated abrasives, wet or dry sand blasting, suitable for ultra-precision grinding and polishing in the crystal and electronic industries and the production of advanced refractory materials. Suitable for processing quenched steel, alloy steel, high-speed steel, high-carbon steel and other materials with relatively hard hardness and high tensile strength. It can also be used as catalyst, insulator and precision casting sand.
