Now you can manufacture customized alumina

components quickly and at a fraction of the cost.

 

Accumet’s ready-to-press alumina powders are available as 96% and 99.7% pure Al2O3

These formulated alumina powders can be formed into dense alumina ceramic components via uniaxial or cold isostatic pressing and sintering.  They are completely homogeneous, guaranteeing constant physical and chemical properties.  Applications include electrical insulators, machine parts, chemical resistant, ballistic, and engineered ceramics.
