Corundum Abrasives and Silicon Carbide Abrasives
Artificial abrasive products are mainly divided into two categories: corundum abrasives and silicon carbide abrasives. Specifically, there are basically the following types:
1. Brown corundum abrasive, the main component is Al2O3, with medium hardness, high toughness, sharp particles, relatively low price, suitable for processing metals with high tensile strength. Both microcrystalline corundum abrasives and black corundum abrasives are derived species.
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, has good self-sharpening, low heat generation, strong grinding ability and high efficiency. The chromium corundum abrasive is its derivative species.
3. Single crystal corundum abrasive, its particles are composed of a single crystal, and have a good multi-edge cutting edge, high hardness and toughness, strong grinding ability, low grinding heat, 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
Suitable for surface deburring, chamfering, descaling and surface polishing of machinery, electronics, metal parts, hardware, tools, auto parts, instrumentation, casting, medical treatment, craft jewelry and other industries.
High grinding efficiency, wear-resistant and durable, not easy to get stuck, high surface brightness!
