Product Description
Black corundumu00a0abrasives is high quality bauxite as the main raw material, add a little and then the reducing agent, inu00a0an arc furnace smelting, color black. So Black corundum, also known as low aluminum corundum, is in the electric arc furnace, bauxite smelting in a prepared alumina spinel and iron ore mainly gray-black crystal phase, which is characterized by oxidizing low aluminum content, and there is a certain amount of Fe2O3 (10%) exists, which has a moderate hardness, highu00a0toughness,highu00a0temperature,thermal performance characteristics of a given temperature.
Product Feature
Black corundumu00a0hardness, toughness greater wear sharp edges and corners, strong self-sharpening, grinding less heat,highu00a0polished workpiece cleaning, polishing its performance is much higher than other similar products at home and abroad, the aluminum content more than 82% blacku00a0corunduma hardness, toughness, hardness and softness, wear durability; its adhesion and hydrophilic, easy on the disc; grinding less congestion, less heat, the work will not burn; self-sharpening strong, ergonomics high, and machined surface free of scratches, polishing finish high; more than double the capacity of more thanu00a0brown corundumau00a0polishing, polishing finish raise more than two.
Application / Models
Its unique performance, good grinding and polishing effect of Black corundum, more and more attention and favor of the broad masses of people. Sanshui and a water-type bauxite as raw material in electric arc furnace cooling from high temperature smelting. Basic Black corundumu00a0abrasive material concentration, cutting ability, toughness, hardness and softness, wear resistance, and high efficiency. Black corundumu00a0abrasive, for stainless steel, metal plating and polishing the bottom surface before sandblasting, it is suitable for glass, wood, stone products, such as grinding and polishing and sand blasting.

Black corundumu00a0widely used tableware polishing industry, electroplating before the bottom surface polishing industry, metal surface treatment industry, glass industry, aluminum and stainless steel polish. Is manufacturing resin grinding wheel, cutting disc, emery cloth novel materials. Currently, the most widely used stainless steel tableware and fine polishing kitchenware, lighting lamps motorcycle parts, auto parts and other medium hard materials. Is manufacturing resin grinding wheel, cutting disc, novel abrasive gauze.
