Black corundum performance Black corundum and low aluminum corundum, blue corundum, is in electric arc furnace, the bauxite made by melting a AL2O3 spinel is given priority to with iron ore phase of the colored crystals, its characteristic is AL2O3 content is lower, and has a certain amount of Fe2O3 (10%), and therefore, moderate hardness and great toughness, self-sharpening, good bonding, high durability, produce less heat when grinding, high temperature resistant, not easy to scratch the surface of the workpiece surface roughness is high. Black corundum and low aluminum corundum, blue corundum, is in electric arc furnace, the bauxite made by melting a AL2O3 spinel is given priority to with iron ore phase of the colored crystals, its characteristic is AL2O3 content is lower, and has a certain amount of Fe2O3 (10%), and therefore, moderate hardness and great toughness, self-sharpening, good bonding, high durability, produce less heat when grinding, high temperature resistant, not easy to scratch the surface of the workpiece surface roughness is high. Hei Gangyu use 1, free grinding, such as metal parts electroplating before the bottom polishing, aluminum products. 2, bicycles, motorcycles, sewing machines, watches and clocks parts. Polished 3, lighting, plastic and hardware tools, and is also suitable for sand (rust, glass flower). 4, material processing, manufacturing resin cutting blade, angle grinding and coated abrasives. 5, black corundum sand granularity and powder is particularly suitable for grinding and polishing stainless steel workpieces and oilstone, grinding paste. 6, black corundum section of sand is the preferred material for non slip road and coal pit storage. Matters needing attention: 1, transport and handling: in the transport process, not drag hook, should prevent mixed with the solid material, strong vibration, friction, hit, hit, forbid throwing should be lightly armed light discharge to reduce black corundum breakage of packing, the impact of the use. 2, storage: should be stored in a cool and dry place, to prevent internal and external packaging bag break, prevent moisture and adsorption of other substances in the air, affect the use effect. It is strictly prohibited to mix with poisonous and harmful gas or volatile matter, and keep away from the source of pollution.
