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. Also available in special Tight Tolerance Plates (contact customer service for details) We offer Macor Rods, Macor Plates, and Macor Parts to your specifications Stocked in Our New York, California, Texas, Singapore & Taiwan Locations.
