Brown corundum, the “tooth of industry”.
Brown corundum abrasive, also known as adamantine, is a corundum material made from high quality abrasive grade bauxite as the main raw material, which is refined in a high temperature electric arc furnace at more than 2250℃. It has excellent properties such as high hardness (hardness of 9, second only to diamond), high thermal stability, high wear resistance, high toughness, and excellent self-locking and low thermal conductivity, which make brown corundum abrasives have a wide range of applications in a number of industrial fields.
