What is white emery?
emery is generally considered to be brown corundum, but gradually in the abrasive industry emery has become a general term for abrasives, including white corundum, black corundum, pink corundum, zirconium corundum, black silicon carbide and green silicon carbide,
So in general, if we say white emery, it refers to white corundum, which is made of high-quality aluminum oxide powder and crystallized by electric melting. Its hardness is slightly higher than that of brown corundum, its toughness is slightly lower, and its purity is high. Good grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance, high temperature resistance and good thermal stability. It is used to make abrasive tools, suitable for grinding high-carbon steel, high-speed steel and stainless steel and other fine-grained abrasives. It is mainly used for sandblasting, grinding and polishing to produce abrasive tools, oil stone, ceramic film coating, etc.
