White corundum

White corundum is made of alumina powder, smelted at high temperature, then cooled and crushed and graded to be white. The white corundum produced by our company has the characteristics of stable product quality, uniform particle size composition, low magnetic content, high bulk density, high hardness, good toughness and high cleanliness. The abrasives made of it are suitable for grinding high carbon steel, high speed steel and hardened steel. It can be used as grinding and polishing material, precision casting sand, spraying material, chemical catalyst carrier, special ceramics, advanced refractory materials, etc.

As a coated abrasive,white corundum is an extremely strong material for erosion and grinding. Due to its sharp and angular particle shape, it is suitable for grinding soft materials (wood, plastic) without blockage.
