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.
