abrasive tool abrasive material WA white adamantine spar polishing sand blast precision foundry
Product name:white fused alumina
specification: 12#
Product introduction:
White fused alumina is made of high quality aluminum oxide powder as raw material, refined and crystalline by electromelting, with high purity, good self-sharpness, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than brown corundum, slightly lower toughness, high purity, good self-sharpness, strong grinding ability, small heat value, high efficiency, acid and alkali corrosion resistance, high temperature and thermal stability. Made of grinding tools, suitable for grinding high carbon steel, high speed steel and stainless steel and other fine-grained abrasive materials can also be used in precision casting and advanced refractory materials.
White corundum performance: white, harder and brittle than brown corundum, strong cutting force, good chemical stability, with good insulation.
