元豐黑剛玉是以礬土為主要原料，加還原劑而后在電弧爐內經高溫冶煉而成，色澤呈黑色，硬度適中，其韌性較大耐磨棱角比較鋒利，自銳性比較強，磨削是發熱量比較少，拋光加工工件潔度比較高，黑剛玉磨料基本料比較集中，切削力比較強，韌性比較大，剛柔相濟，耐磨性比較好，工效比較高。

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晶體，其特點是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、韌性比較高、比較耐高溫、熱態性能比較溫定的特點。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，砂布的比較好的磨料。黑剛玉磨料基本粒比較集中，切削力比較強，韌性比較大，剛柔相濟，耐磨性比較好，工效比較高。

元豐黑剛玉磨料適用于不銹鋼，金屬制品電鍍前底面拋光和噴沙，它適用于玻璃、竹木、石材等制品的磨削和拋光．黑剛玉應用于餐具拋光行業，電鍍前底面拋光行業，金屬表面處理行業，玻璃制品行業，鋁制品和不銹鋼的拋光，又是制造樹脂砂輪，切割片，砂布的材料。

Black corundum profile

Black corundum is with high grade bauxite as main raw materials, and reducing agent, and then in the Canon of high temperature smelting electric arc furnace and become, in black color, moderate hardness, wear-resisting sharp edges and corners, which has less toughness self-sharpening, grinding is less calorific value, high pure degree of polishing machining, basic material concentration, black corundum abrasive cutting force is strong, toughness, flexibility, good abrasion resistance, high working efficiency.

Black corundum and low aluminum corundum, is in the electric arc furnace in bauxite made by melting a is given priority to with alpha Al2O3 and spinel mineral phase - 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. 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. 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 abrasives has important status and role in mechanical processing, is with the grinding machining this way has the characteristics of the inseparable. In machining, black corundum grinding grain can be a free state, can also be a consolidation state; Can be used in a mechanical processing, also can use manual processing. Black corundum abrasives in the form of processing, the main use of grinding, grinding and polishing.

Black corundum purposes

Black corundum abrasives suitable for stainless steel, metal plating before floor polishing and spray sand, it is suitable for products such as glass, wood, stone grinding and polishing. Black corundum is widely used in tableware polishing industry, floor polishing industry before electroplating, metal surface treatment industry, glass industry, aluminum and stainless steel polishing, making resin grinding wheel, cutting slices, emery cloth, new materials at present, the most widely used in stainless steel kitchen utensils and appliances, lighting lamps and lanterns of motorcycle parts, auto parts and other medium hardness materials fine polishing.

1, free grinding, such as floor polishing before plating metal parts, aluminum products, parts of bicycle, motorcycle, sewing machines, watches and clocks.

2, lamp act the role ofing, plastic and hardware tools, such as polishing, is also suitable for sandblasting (spray derusting, glass flower).

3, processing and manufacturing resin cutting, Angle grinding pills and coated abrasive, etc.

4, black corundum sａnd granularity and micro powder particularly suitable for grinding and polishing of stainless steel workpieces and sharpening stone, grinding paste manufacturing.

5, black corundum sａnd antiskid pavement and coal mine under storage material of choice.
