Macor Machinable Glass Ceramic
Macor Machinable Glass Ceramic, Machined With Conventional Metalworking Tools
Macor machinable glass ceramic has the versatility of a high performance polymer, the machinability of a metal, and the performance of an advanced technical ceramic. It is a hybrid glass-ceramic and offers a unique combination of properties from both families of materials. Macor is an excellent electrical and thermal insulator, and offers good performance in high temperature, vacuum, and corrosive environments.
One of the main advantages of Macor is that it can be machined with conventional metalworking tools. This allows for significantly faster turnarounds and substantially lower production costs when compared with other technical ceramics, making it an excellent material for both prototyping and medium-volume production runs.
