AL2O3 white alundum powder, abrasive material white corundum price
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. It 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.
