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 produce complex shapes and precise parts with tight tolerances. The glass ceramic can be CNC machined with conventional HSS tools commonly used for metal machining. As a result, expensive specialized machinery and diamond tooling are typically not required to machine MACOR® material. Learn more about the machining parameters of MACOR® in our Machining Guidelines.

MACOR® can be used at temperatures of up to 800°C for long periods of time and can withstand up to 1000°C without load. In addition, the unique glass ceramic has zero porosity and is non-wetting. MACOR® does not deform or outgas allowing it to be used in vacuum environments. The material is an excellent insulator for high voltages at various frequencies. MACOR® sets an industrial standard for machinable glass ceramic that is difficult for other MGC materials to match. It is ideal for a wide range of applications in the aerospace, medical and semiconductor industries.
Our company stocks MACOR® as semi-finished sheets, rods, and bars (see table) with short lead times. These are the starting materials for complex shaped parts.
