MACOR® Rod, 0.500"DIA x 12"L

MACOR® Machinable Glass Ceramic (MGC) has a continuous use temperature of 800°C and a peak temperature of 1000°C. Its coefficient of thermal expansion readily matches most metals and sealing glasses. It 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. It is a clean material with zero porosity and no out-gassing.
Rod diameter tolerance: +.015" / -.000"

Machining tolerances: detail machining to .0005"; surface finish of less than 20µin and polishing to a smoothness of 0.5µin.-AA.

This item is suitable for making:
Electric and thermal insulators, Electronic tube parts, Gas nozzles, Heat shields, Heat sinks, Induction heating parts, Laser tubes and tips
