Aluminium Powder Alumina Oxide Powder for Polishing Car Glass Optic and Lens
Aluminium Oxide Powder Introduction
Alumina powder is a high-purity, fine-grained material made from aluminum oxide (Al2O3) that is widely used in a variety of industrial applications. It is a white crystalline powder that is typically produced through the refining of bauxite ore. Alumina powder has a range of desirable properties, including high hardness, chemical resistance, and electrical insulation, which make it a valuable material in many industries.
