MACOR® is an outstanding technical material offering huge benefits in terms of machining. MACOR® is a white, non-wetting, odour-free, non-porous and outgassing-free material.

It lends itself exceptionally well to machining. The production tolerances of MACOR® are surprisingly tight (+/- 0.01 mm, surface finish < 0.5 µm and polished < 0.013 µm) for complicated shapes. MACOR® remains uniformly stable at 800 °C, peaking at 1000°C without load. Unlike ductile materials, it will not creep or deform.

Its coefficient of thermal expansion is equal to that of most metals and glass solder. As an electrical insulator – particularly at high temperatures – the material is outstanding at high voltages and over a broad frequency spectrum.
