Abrasive products are mainly divided abrasive corundum

ilicon 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 mini flap disc  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 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  non woven flap wheel 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 abrasive cloth belt  silicon carbide abrasives, silicon carbide abrasive cerium , is silicon carbide abrasive, the 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.
