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.
