The hardness of white corundum is slightly higher than that of brown corundum, but the toughness is slightly poor. It is easy to cut into work during grinding. It has good self-sharpness, low calorific value, strong grinding ability, high efficiency and higher price than brown corundum. oil stone for polishing is suitable for high hardness steel such as high-speed steel and alloy steel.
