Alpha Aluminum Oxide Alumina Powder for Polishing
Alumina powder, also known as aluminium oxide or activated alumina, is a chemical compound that is mainly used to produce aluminium.
Alumina powder is the ideal for aluminium production and others that require hardness and resistance to abrasion or other forms of chemical wear. Alumina powder is also ideal for products that require corrosion and wear resistance, and for products that require
high thermal conductivity, such electrically and thermally insulating applications.
