MACOR® Machinable Glass Ceramic Rod

MACOR® Machinable Glass Ceramic Rod is a versatile composite of fluorophlogopite mica and borosilicate glass, engineered to deliver high dielectric strength, zero porosity, and resistance to temperatures up to 1000 °C in air. It can be machined with standard metal tools, enabling high-precision shaping without post-firing, making it ideal for small-scale prototyping and intricate component design. Common applications span aerospace insulators, medical laser apertures, RF-resistant parts, and ultra-clean vacuum chamber components. Specific uses include test substrates for microwave dielectric tuning, pinhole fixtures in dental lasers, and outgassing-free supports in optical alignment systems. Its consistent thermal stability and stress-resistance under impact and fatigue conditions also make it a focus in dynamic ceramics and energy-dissipation material studies. The MACOR® rod's unique ability to bridge machinability with insulating and structural robustness positions it as an enabling material in both cutting-edge scientific instruments and custom industrial tooling.
