Among them, abrasive products are mainly divided into two categories: corundum abrasives and silicon carbide abrasives. Specifically, there are basically the following:
1. Brown corundum abrasive, the main component is Al2O3, with medium hardness, high toughness, sharp particles, relatively low price, suitable for processing high tensile strength metals. Microcrystalline corundum abrasives and black corundum abrasives are all derived varieties.
2. White corundum abrasive, its hardness is slightly higher than brown corundum, but the toughness is poor, easy to cut into the workpiece during grinding, self-sharpening, less heat, strong polishing ability, high efficiency. Chrome corundum abrasive is a derivative of its origin.
3.Single-crystal corundum abrasive, the particles are composed of a single crystal, and it has a good multi-edge cutting edge, high hardness and toughness, strong grinding ability, less heat generation, the disadvantage is higher production costs , production is 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 abrasive, green silicon carbide abrasive, cubic silicon carbide abrasive, silicon carbide abrasive, etc., belonging to silicon carbide abrasive, the main component is SiC silicon carbide, high hardness, brittleness, sharp abrasive grain, good thermal conductivity, strong wear resistance, suitable for processing hard and brittle metal and non-metal products.
