High Grade Black Alumina

By monitoring the development of the market, we are betrothed in manufacturing and exporting an exclusive array of High Grade Black Alumina in Shizuishan, Ningxia Hui, China.

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.
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.
