Macor Machinable Glass

MACOR® Machinable Glass Ceramic

• is Machinable with ordinary metal working tools
• allows Fast Turnaround, no firing required
• holds High Temperatures, to 0.01 mm / 0.0005 in.
• withstands High Temperature, up to 1000° C
• is Vacuum Compatible, no outgassing and zero porosity

With MACOR® Machinable Glass Ceramic, fabrication is fast - because it can be machined into complicated shapes and precision parts with ordinary metal working tools, quickly and inexpensively, and it requires no firing after machining.

MACOR ® is available in round bar, sheet or rectangular bar.
