Abrasive products are mainly divided abrasive corundum

carbide abrasive two categories, specifically, there are basically the following: corundum abrasive, the main component of Al2O3, with medium hardness, toughness, particle Fengrui, relatively inexpensive, suitable for machining high tensile strength of the metal. Microcrystalline corundum abrasives and black corundum abrasives are its derived varieties; corundum abrasive, slightly higher than the hardness of corundum, but poor  paper disc toughness, easy to cut into the workpiece during grinding, good self-sharpening, less heat, grinding ability, and high efficiency. Chromium corundum abrasive is its derived varieties.
Another crystal corundum abrasive material particles are composed of a single crystal, and has a good polygonal cutting edge, high hardness and toughness, grinding ability, less grinding heat, the disadvantage is the high cost of production, lower yield, so the price is relatively high, zirconium corundum abrasives is crystalline compound, slightly lower hardness, crystal size is fine, good wear resistance; black silicon carbide abrasive, green silicon carbide abrasive, cubic silicon carbide abrasives, silicon carbide abrasive cerium , is silicon carbide abrasive, the nonwoven belt  main ingredient is silicon carbide SiC, high hardness, brittleness, sharp abrasive grains, good thermal conductivity, wear resistance stronger, more suitable for processing brittle metals and non-metallic products.
Abrasives and abrasive products typically include superhard abrasive material into two categories: ordinary abrasive refers to the ordinary abrasive made of abrasive. Press abrasive combined into the  velcro disc form of bonded and coated abrasives, while the binding agent can be divided into different ceramic abrasive, abrasive resins, rubber, abrasive, magnesite abrasive series; superhard abrasive material , mainly in the metal powder, metal oxides or other superhard material CBN as a filler, may also be appropriate to add ordinary abrasive (such as Al2O3, SiC, etc.), binding agents or with resin or vitrified abrasive made of a metal binding agent .
