黑刚玉又名低铝刚玉，是于电弧炉中，将铝矾土熔炼而制得的一种以α- 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左右）存在，因而具有硬度适中、韧性高、耐高温、热态性能稳定的特点。

     黑刚玉多用于自由研磨，如制品电镀前的打磨工粗磨，主要用于不锈钢，金属制品，光学玻璃，竹木制品的抛光和喷砂，又是制造树脂砂轮，切割片，砂布的新颖磨料。本公司黑刚玉磨料基本粒集中，切削力强，韧性大，刚柔相济，耐磨性好，工效高。是磨削抛光、喷砂不锈钢制品的理想产品。

     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优质材料。

Black corundum and low aluminum corundum, is in electric arc furnace, the bauxite made by melting a is given priority to with alpha Al2O3 and spinel mineral phase of the colored crystals, its characteristic is Al2O3 content is lower, and has a certain amount of Fe2O3 (10), thus has moderate hardness, high toughness, high temperature resistant, thermal steady state performance characteristics.
Black corundum more for free grinding, such as the beat of the products before electroplating grinder coarse grinding, it is mainly used for stainless steel, metal products, optical glass, bamboo and wood products polishing and sanding, making resin grinding wheel, cutting slices, new abrasive cloth.The company black corundum abrasive basic particle concentration, strong cutting force, tenacity is big, and flexibility, good abrasion resistance, high working efficiency.Grinding polishing, sandblasting stainless steel products is the ideal product.
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.
