Macor is a machinable glass-ceramic made from fluorophlogopite mica crystals embedded in a borosilicate glass matrix. This composition gives it a rare
combination of metal-like machinability, excellent electrical insulation, low thermal conductivity, and stability up to 1000°C (no load) while maintaining very tight tolerances.
