Macor Machinable Glass Ceramic

Macor Machinable Glass Ceramic

MACOR ® machineable glass ceramic has a continuous use temperature of 800ºC and a peak temperature of 1000ºC. Its coefficient of thermal expansion readily matches most metals and sealing glasses. MACOR is non-wetting, exhibits zero porosity, and unlike ductile materials, won't deform. It is an excellent insulator at high voltages, various frequencies and high temperatures. When properly baked out, it won't outgas in vacuum environments.

It can be machined into complicated shapes and precision parts with ordinary metal working tools, quickly and inexpensively, and it requires no post firing after machining. That means no frustrating delays, no expensive hardware, no post fabrication shrinkage, and no costly diamond tools to meet specifications.

The Technical Ceramics business of Morgan Advanced Materials is an approved distributor of Corning MACOR ® through our facility in Fairfield NJ USA.
