Description:
White fused aluminum oxide is a kind of WA abrasive grain, it is made by electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. White fused aluminum oxide is also characterized by its high purity, ability of self-sharpening, better cutting,less heat emit, higher efficiency, acid and alkali resistance, good thermal stability.
Applications:
WAMB is a bonded white fused aluminum oxide abrasive grain suitable for making abrasive stone, oil stone or for refractory coating and anti-skid tile, as loose grains, it widely used for pressure blasting and polishing.
WAE-17 is a kind of bonded white fused aluminum oxide abrasive grain suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for polishing, precision casting, spring and coating.
WAP is a coated white fused aluminum oxide abrasive grain, can be well used for many kinds of coated abrasives like sanding paper, sanding cloth, and sanding belt.
