Macor has a continuous use temperature of 800°C, and a peak temperature of 1000°C. Its coefficient of thermal expansion matches most metals and sealing glasses, meaning it can perform in harsh operating environments where precision is a necessity. It can also be machined in intricate shapes and precision parts. With no post firing required after machining. Macor is clean, offering zero porosity and no out gassing.

Macor is a unique and flexible material that boasts the performance of a technical ceramic, whilst retaining the versatility of a high-performance polymer and the machinability of a soft metal. Macor remains stable at high temperatures and pressure; it can very quickly be designed into complex parts using conventional metalworking tools.

Macor ceramic machines differently from metal, but an experienced machinist should be able to achieve excellent results after becoming familiar with the material. The ability to machine Macor holding tight tolerances means it can be adapted to a wide variety of applications.
