　　黑刚玉简介：Black corundum profile

　　黑刚玉又名低铝刚玉、青刚玉，是于电弧炉中，将铝矾土熔炼而制得的一种AL2O3和铁尖晶石为主矿相的灰黑色结晶体，其特点是AL2O3含量较低，并有一定量的Fe2O3(10%)存在，因而具有硬度适中、韧性大、自锐性、粘结性良好，耐用度高，磨削时发热少，耐高温，不易划伤工件表面，工件表面光洁度高等特点。

　　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.

　　黑刚玉用途：Black corundum purposes

　　黑刚玉主要应用于自由研磨，如金属零件电镀前底面抛光、铝制品，适用于自行车、摩托车、缝纫机、钟表零部件、灯饰、塑胶及五金工具等的抛光，亦适用于喷砂(除锈、玻璃喷花)，加工材料，制造树脂切割片、角磨片和涂附磨具等。黑刚玉粒度砂和微粉特别适合于不锈钢工件的研磨抛光及油石、研磨膏的制造，黑刚玉段砂更是防滑路面和煤矿坑下仓储的首选材料。

　　Black corundum is mainly used in free grinding, such as floor polishing before plating metal parts, aluminum products, suitable for bicycle, motorcycle, sewing machine, clock parts, lamp act the role ofing, plastic and hardware tools, such as polishing, is also suitable for sandblasting (spray derusting, glass flower), materials processing, manufacturing resin cutting, Angle grinding pills and coated abrasive, etc.Black corundum sand granularity and micro powder particularly suitable for grinding and polishing of stainless steel workpieces and sharpening stone, grinding paste, black corundum sand antiskid pavement and coal mine under the storage and the material of choice.
