Macor Machinable Glass Ceramic Disc as High Voltage Electrical Insulators

Product Description

Product Description

Macor Machinable Glass Ceramic (MGC) performs like an advanced technical ceramic while having the versatility of a high-performance polymer and the machinability of a metal. It is a unique blend of characteristics from both families of materials and it is a  hybrid glass-ceramic. In high temperature, vacuum, and corrosive situations, Macor performs well as an electrical and thermal insulator.

 

The fact that Macor can be machined using common metalworking tools is one of its key benefits. When compared to other technical ceramics, this enables noticeably quicker turnaround times and significantly reduced production costs, making it a superb material for both prototype and medium-volume production runs.

  

Macor has no pores and won't outgas when baked out properly. Unlike high temperature polymers, it is tough and rigid and won't creep or deform. Radiation resistance also applies to Macor machinable glass ceramic.

 

According to your specifications, we provide Macor Rods, Macor Sheets, and Macor Components.

 

Typical Properties	Zero porosity Low thermal conductivity Very tight machining tolerances Outstanding dimensional stability Excellent electric insulator for high voltages Won't cause outgassing in vacuum environment Can be machined using common metalworking tools
Typical Applications	Coil supports Laser cavity components High-intensity lamp reflectors High-voltage electrical insulators Electrical spacers in vacuum systems Thermal insulators in heated or cooled assemblies
