Aluminum oxide abrasive cloth is a kind of inorganic material with high hardness, high density, and high temperature stability, which is mainly composed of aluminum oxide and other rare earth elements. Its particles are mostly in the form of plates, spheres, or blocks, with high wear resistance and mechanical strength. In addition, aluminum oxide abrasive cloth is able to maintain better performance in harsh environments such as high temperature, high pressure, and corrosion.
