? ? ?黑剛玉又名低鋁剛玉，是于電弧爐中，將鋁礬土熔煉而制得的一種以α-?Al2O3?和鐵尖晶石為主礦相的灰黑色結(jié)晶體，其特點(diǎn)是Al2O3?含量較低，并有一定量的Fe2O3（10左右）存在，因而具有硬度適中、韌性高、耐高溫、熱態(tài)性能穩(wěn)定的特點(diǎn)。
?
? ? ?黑剛玉多用于自由研磨，如制品電鍍前的打磨工粗磨，主要用于不銹鋼，金屬制品，光學(xué)玻璃，竹木制品的拋光和噴砂，又是制造樹脂砂輪，切割片，砂布的新穎磨料。本公司黑剛玉磨料基本粒集中，切削力強(qiáng)，韌性大，剛?cè)嵯酀?jì)，耐磨性好，工效高。是磨削拋光、噴砂不銹鋼制品的理想產(chǎn)品。

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.
