Precision Ceramics USA is one of the principal, longest serving and highly-respected worldwide distributors for Macor® Machinable Glass Ceramic - a unique material combining the performance of a technical ceramic with the versatility of a high performance plastic. |
Macor machinable glass ceramic is a white, odourless, porcelain-like (in appearance) material composed of approximately 55% fluorophlogopite mica and 45% borosilicate glass.
It has no known toxic effects; however, the dust created in machining can be an irritant. This irritation can be avoided by good housekeeping and appropriate cleaning techniques.
The material contains the following compounds:

Microstructure
The photograph below shows the microstructure of Macor glass machinable ceramic with 5000x magnification. Randomly oriented mica flakes in the microstructure of Macor glass machinable ceramic are the keyo its machinability.
Macor is an outstanding engineering material and is machinable with ordinary metalworking tools. Macor is also a problem solving material combining the performance of a technical ceramic with the versatility of a high performance plastic.
Macor has a high use temperature (800°C continuous to 1,000°C peak). It has a low thermal conductivity and is a useful high temperature insulator as well as an excellent electrical insulator. Macor has no porosity and when properly baked out, will not outgas. It is strong and rigid and, unlike high temperature plastics, will not creep or deform. Macor is also radiation resistant.
Macor is pure white and can be highly polished. It can be thick or thin film metallised, brazed and epoxy bonded. Another major advantage of this unique material is that, even in small quantities, components are economical to manufacture.
