Properties of Alumina Al2O3

Alumina (Al2O3) is a hard, chemically resistant material and has the ability to withstand very high temperatures in aggressive environments. Innovacera offers Alumina with various purity levels, including 99.8% and 99.0%. The level of purity, grain size, and density required is dependent on the rigors of the application and the component configuration.
