Applications
White fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory materials.
Advantages
1) Not affecting the color of the processing cases.
2) Sandblasting in the non-iron process.
3) High speed processing.
4) Very low amount of iron oxide, suitable for non-ferrous blasting operations.
Description:
White fused alumina is based on high-quality aluminum oxide powder as raw material, formed by the crystallization of fused refining, high purity, self-sharpening, good acid and alkali corrosion, high temperature thermal stability performance,
White fused alumina is slightly higher than the brown corundum hardness, toughness is slightly lower, high purity, self-sharpening good grinding ability, heat a small, high efficiency, acid and alkali corrosion, high temperature thermal stability. Made with its abrasive for grinding high-carbon copper, high-speed steel.
