MACOR® Machinable Glass Ceramic Sheet

MACOR® Machinable Glass Ceramic Sheet is a high-performance, composite material uniquely designed to offer the benefits of both ceramics and machinability. With a microstructure that inhibits crack propagation, MACOR combines strength, thermal stability, and ease of fabrication. This ceramic can be machined with standard metal tools to tight tolerances, without the need for post-firing, making it highly cost-effective for prototyping and custom components. Its impressive mechanical properties include a compressive strength of up to 50,000 psi and a tensile strength of 15,000 psi. The material remains stable at temperatures up to 1000°C, is thermally shock resistant, and exhibits low thermal conductivity with a high thermal expansion coefficient matching that of soda-lime glass. It is zero-porosity and vacuum-tight, making it ideal for demanding applications. MACOR is widely used in industries such as aerospace, vacuum systems, medical instrumentation, and semiconductor manufacturing. Specific uses include vacuum feedthroughs, insulators, electrical connectors, and structural supports in high-temperature or high-vacuum environments. In research and innovation, its unique sealing compatibility with metals, glass, and ceramics enables the development of advanced components for high-vacuum experiments and microwave systems.
