Machinable glass ceramics 

Machinable glass-ceramic is a new class of ceramic material which is capable of being machined to precise tolerances using conventional metal-working tools and equipment. There are a number of useful machining techniques which are pertinent to this material. Details of the individual operations; turning, milling, drilling, tapping, etc. are outlined.

MACOR® Machinable Glass Ceramic

Macor is a machinable glass ceramic material that possesses outstanding engineering properties. Unlike other ceramics, Macor can be machined with ordinary metalworking tools. This problem solving material combines the performance of a technical ceramic with the versatility of a high performance plastic. Macor has no porosity and when properly baked out, will not outgas. It is strong and rigid and, unlike high temperature plastics, will not creep or deform. Macor machinable glass ceramic is also radiation resistant.

Properties of MACOR® Glass Ceramic 

MACOR® has a continuous use temperature of 800°C and a peak temperature of 1000°C. It offers excellent high-temperature electrical insulation properties with an electrical breakdown strength of 40KV/A per millimeter.

Industry Applications MACOR® builds value in every field :

• Constant and ultra-high vacuum  environments 

• Laser technology 

• Semiconductor / Electronic 

• Aerospace / Space 

• Medical/ Laboratory equipment 

• Fixtures 

• Chemical
