Alumina 960 machinable ceramic

Alumina 960 - Machinable ceramic

Final Advanced Materials provides Al2O3 machinable ceramics. Cotronics® machinable Alumina is available in boards and rods, we can machine according to your drawings.

Cotronics® Rescor® 960 is a 96% Alumina machinable ceramic that is usable to 1650°C. It is manufactured from high purity alumina by a unique process.

Machining can be accomplished with conventional tooling on standard shop equipment. No heat treatment is required. Rescor® 960 machinable Alumina can be used continuously to temperatures of 1650°C and offers the convenience and economy of an in house capability for Alumina parts. The chemical, thermal and electrical properties of Rescor® 960 is equivalent to standard high alumina ceramics.
