>Alumina 96% Machinable Material Properties.
useable continually to 1650°C with a melting point of 1870°C, 96%
Alumina machinable ceramic is manufactured from high purity alumina
by a unique process. Unlike standard alumina this unique
manufacturing process enables our 96% Alumina to be machined with
conventional tooling on standard machine shop equipment. No post
heat treating after machining is required offering the convenience
and economy of an in house capability for alumina parts. The
chemical, thermal and electrical properties of our 96% Alumina
machinable ceramic are equivalent to standard high alumina ceramics,
with good resistance to thermal shock. Our Alumina 96% machinable
ceramic is available in various standard rod sizes up to
Ø3.5" x 12"
long, and plates up to 6" x 6" x ¾".
