Machinable Glass Ceramic Bar:

Machinable Glass Ceramic is used widely because of its special property. The most important feture is its machinability. It can be quickly, accurately and economically machined into high-precision components using ordinary metalworking tools and does not require any post-firing after machining has been completed. Moreover, it has the same temperature resistance up to 1000ºC. Its low thermal conductivity is also one of valuable properties. The manufacturing time and cost is reduced because the post-firing process has been removed.

Advantages of Macor Ceramic Rod:

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
