Accumet Materials Co

Accumet Materials Co.

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%, 99% 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.
