Macor Machinable Glass Ceramic

Macor Machinable Glass Ceramic, it can be 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.

Macor Properties

Mechanical Properties

Macor machinable glass ceramic is strong and rigid. Unlike high temperature plastics, Macor will not creep or deform. It has zero porosity and can be polished to a smoothness of 0.5µin.

Thermal Properties

Unlike high temperature plastics, Macor will not creep or deform. It has low thermal conductivity, which makes it useful as a high temperature insulator. Macor has excellent dimensional stability in a variety of environments (heat, radiation, etc.). It’s coefficient of thermal expansion readily matches most metals and sealing glasses.

Macor Machining

Macor is one of the few ceramics that can be machined using regular metal working tools. While there is a learning curve to machining Macor, it is certainly achievable for someone with the correct skills and patience. The machining characteristics of Macor are very different from metals and plastics so we recommend you take some time to practice drilling, turning, and milling the Macor before you try to make your own component to understand how it behaves. Unlike plastics and metals, ceramics never plastically deform; this means that when machining Macor you must be very conscious of chipping.

Industrial Ceramicparts is your Macor machinable glass ceramic specialist for your technical ceramic prototyping & manufacturing needs. We are always happy to use our many years of advanced ceramics experience to provide advice on materials, design, and application.
