Alumina

Omega is a supplier of high quality alumina components. These materials offer excellent wear resistance, electrical and thermal insulation characteristics, as well as high temperature strength. They are also exceptional in abrasive and corrosive environments.

Parts are produced by extrusion, slip casting, and dry pressing methods.

We offer a wide range of shapes, sizes, and purity levels, to meet your requirements. We handle prototype to large blanket quantities.

See our chart for physical properties. Custom purities are also available.
