- MACHINABLE with ordinary metal working tools
- Allows FAST TURNAROUND. No post firing required
- Holds TIGHT TOLERANCES, up to .0005"
- Withstands HIGH TEMPERATURES, up to 1000°C (no load)
- Is CLEAN, no outgasing and zero porosity.
With MACOR Machinable Glass Ceramic (MGC), fabrication is fast because 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.
MACOR® Machinable Glass Ceramic 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. When properly baked out, it won't outgas in vacuum environments.
Machining tolerances are surprisingly tight, up to .0005". It can be machined to a surface finish of less than 20µin. and polished to a smoothness of 0.5µin.-Ra. Configurations are limited only by vailable equipment and the experience of the machinist.
Sealing, Joining and Metalizing
MACOR MGC can also be joined or sealed - both to itself and to other materials - in a number of ways; metalized parts can be soldered together and brazing has proven an effective method of joining the material to various metals; epoxy produces a strong joint, and sealing glass creates a vacuum tight seal. Even a straightforward mechanical joint is possible.
It can be thick film metalized using metal inks, or thin film metalized by sputtering.
