1. Brown corundum abrasive, the main component is Al2O3, which has medium hardness, high toughness, sharp particles, relatively low price, and is suitable for processing metals with high tensile strength. Both microcrystalline corundum abrasive and black corundum abrasive are its derivatives.
2. The hardness of white corundum abrasive is slightly higher than that of brown corundum, but its toughness is poor. It is easy to cut into the workpiece during grinding. It has good self-sharpness, low calorific value, strong grinding ability and high efficiency. Chrome corundum abrasive is a derivative of it.
3. Single crystal corundum abrasive, its particles are composed of a single crystal, and has a good multi-edged cutting edge, high hardness and toughness, strong grinding ability, and low grinding calorific value. The disadvantage is that the production cost is high and the output lower, so the price is higher. Zirconium corundum abrasive is also a crystalline compound with slightly lower hardness, finer 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 component is silicon carbide SiC, which has high hardness, high brittleness, sharp abrasive grains and good thermal conductivity. Strong wear resistance, more suitable for processing hard and brittle metal and non-metal products.
