Macor Machinable Glass Ceramic Technical Data

Key Services & Products

Macor is an outstanding engineering material and is machinable with ordinary metalworking tools. Macor is also a problem solving material combining the performance of a technical ceramic with the versatility of a high performance plastic...

	Macor has a high use temperature (800°C continuous; 1000°C peak)
	Macor has a low thermal conductivity and is a useful high temperature insulator
	Macor is an excellent electrical insulator and is used extensively throughout the semiconductor and electronic industries
	Macor has no porosity and when properly baked, will not outgas. Macor is widely used in ultra high vacuum applications
	Macor is strong and rigid. Macor unlike high temperature plastics will not creep or deform
	Macor is radiation resistant and plays a key role in nuclear applications and nuclear-related experiments and research & development
	Macor can be thick or thin film metallized, brazed, epoxy and frit bonded
	Macor is white and can be highly polished. Macor is the perfect material for medical and optical devices

Macor has a high use temperature (800°C continuous to 1,000°C peak). It has a low thermal conductivity and is a useful high temperature insulator as well as an excellent electrical insulator. 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 is also radiation resistant.

Macor is pure white and can be highly polished. It can be thick or thin film metallised, brazed and epoxy bonded. Another major advantage of this unique material is that, even in small quantities, components are economical to manufacture.

Macor is now manufactured exclusively in France by Corning Incorporated and Precision Ceramics is the UK's principal distributor for this unique machinable glass ceramic.
