Machineable Glass: MACOR

By Ceramic Oxide Fabricators Australia

  • is Machinable with ordinary metal working tools
  • allows Fast Turnaround, no firing required
  • holds Tight Tolerances, 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.

Thermal Properties

Coefficient of expansion 100 x 10-7/ °C
Continuous operating temperature 800 °C (1000 °C, no load)

Mechanical Properties

Density 2.52 g/cm3
Porosity nil
Hardness 48 Rockwell A
Flexural Strength 94 MPa

Electrical Properties

Dielectric strength 40kV/mm
Volume resistivity Over 1016 ohm-cm at 25 °C, over 107 at 400 °C.

Chemical Properties

Good resistance to common acids and alkalis, even at 95 °C.

The Point is This:

When you need the performance of a technical ceramic - (high use temperature, electrical resistivity, zero porosity) - and your application demands the ready fabrication of a complicated shape, look for MACOR® Machineable Glass Ceramic.
