1. Brown corundum abrasive, mainly composed of Al2O3, has medium hardness, large toughness, sharp particles and low price, and is suitable for processing metals with high tensile strength. Both microcrystalline corundum abrasive and black corundum abrasive are its derivatives.

2. White corundum abrasive is slightly harder than brown corundum, but its toughness is poor. It is easy to cut into the workpiece during grinding, with good self sharpening, low heat, strong grinding ability and high efficiency. Chromium corundum abrasive is its derivative.

3. Single crystal corundum abrasive, whose particles are composed of a single crystal, has a good multi edge cutting edge, high hardness and toughness, strong grinding ability, and less grinding heat. Its disadvantage is that the production cost is high and the output is low, so the price is relatively high. Zirconium corundum abrasive is also a crystal compound with slightly low hardness, fine crystal size and good wear resistance.
4. Black silicon carbide abrasives, green silicon carbide abrasives, cubic silicon carbide abrasives, cerium silicon carbide abrasives, etc. belong to silicon carbide abrasives. The main components are silicon carbide SiC, which has high hardness, high brittleness, sharp abrasive particles, good thermal conductivity, and strong wear resistance. It is more suitable for processing hard and brittle metal and non-metallic products.
