Machinable Glass Ceramic Macor Rod 

Machinable ceramic materials have excellent electrical insulation performance (electric breakdown reaches 40kv/a per millimeter), high mechanical strength, and resistance to quenching and heating (resistance to freezing and heating from minus 200 degrees to 800 degrees, and are widely used in welding fixtures, optical glass forming molds, etc.). Its corrosion resistance is also better than ordinary ceramics. Its excellent corrosion resistance makes it applied to all kinds of chemical equipment. Compared with polytetrafluoroethylene, it is more corrosion-resistant, non-aging and long service life. The vacuum outgassing rate of machinable ceramics is very low (widely used in all kinds of vacuum equipment, photovoltaic vacuum coating equipment, etc.). In addition, machinable ceramics also have excellent electromagnetic performance. They have been widely used as various coil frameworks, typically used in missile gyroscope instrument coil frameworks. 

The most outstanding feature of machinable ceramics is its machinability, which can meet the requirements of high-precision technology. Without mold opening, it can be directly processed and formed, greatly reducing the design and processing cycle. Machinable ceramics can be flexibly applied to various occasions that require structural ceramic parts with complex shapes, high precision requirements and difficult forming (such as various ceramic thin walls, ceramic threads, etc.).

Machinable Glass Ceramic Rod Properties : 

Machinable Glass Ceramic rod with  excellent compressive strength, high thermal insulating value, radiation immunity, and excellent dielectrical strength. Unlike plastics, whose temperature resistance and rigidity starts to fall off at as little at 150°C, Macor is non-ductile and is deformation resistant to 800°C (up to 1,000°C with no load or weight-bearing).  Macor is so thermally stable that it is cut into small blocks against which are measured deformations in materials in high temperature, radioactive conditions.

• Very tight machining tolerances of up to 0.0005in (0.013mm).
• Can be machined with normal metalworking tools
• Macor can be thick or thin film metallized, brazed, epoxy and frit bonded
• Won’t outgas in vacuum environment
• Does not require firing after machining
• Strong and rigid; unlike high temperature plastics, Macor will not creep or deform
• Zero porosity
• Can be polished to a smoothness of 0.5µm
