    Materials - Alumina  

Alumina (Al2O3) is a hard, chemically resistant material and has the ability to withstand very high temperatures in aggressive environments. McDanel 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.

Standard McDanel Alumina products include various tubes, rods, crucibles, boats, trays, dishes, and discs that are available for purchase online. We also have significant capabilities for producing custom engineered Alumina products.
