MACOR® machinable glass ceramic from CORNING is a white, odorless, and opaque material consisting of 55 % MIKA and 45 % borosilicate glass. The high-performance glass ceramic offers ideal properties for a wide range of industrial applications. MACOR® can be used to design complex shapes and precise parts with tight tolerances. It can be CNC-machined with conventional HSS tools commonly used for machining metal. As a result, no expensive special equipment, machines, or diamond tools are generally required to process MACOR®. You can find the processing parameters for MACOR® in our machining guidelines.

MACOR® can be used at temperatures of up to 800 °C for long periods of time and withstands up to 1000 °C without load. The unique glass ceramic has zero porosity and is non-wetting. MACOR® does not deform or outgas, so it can also be used in vacuum environments. It is an excellent insulator for high voltages at various frequencies, as it provides low conductivity. MACOR® sets an industrial standard for machinable glass ceramic. It is ideal for a wide range of applications in the aerospace, medical, and semiconductor industries.
