  • Macor allows fast turnaround, no post firing required
  • Holds tight tolerances, up to 0.0005in. (0.013mm)
  • Withstands high temperature, up to 1000°C (no load)
  • Macor is clean, no out gasing and zero porosity.
  • Rapid prototype service - Components finished to your specifications.
  • Research and Development undertaken for your special projects.

When you need the performance of a technical ceramic- (high service temperature, electrical resistivity, zero porosity) – and your application demands the ready fabrication of a complicated shape look at Macor. It will lower costs and substantially reduce the time between design and actual use.


Macor Machinable Glass Ceramic was developed and manufactured by Corning Incorporated for use in the NASA space shuttle space program.  After an extensive testing program by NASA and UCLA it became clear that Macor was more suitable than Silica Glass, Boron Nitride (BN) and Silicon Nitride in certain components and applications.


Over 200 parts of Macor MGC could and can be found on the now retired Space Shuttle Orbiter. Macor is still being used in the Aerospace Industry and in several ongoing space programs around the world today.
