Macor Plate/Sheet/Disc Description
Macor Plate/Sheet/Disc is a high-performance glass-ceramic known for excellent electrical insulation, resistance from -270°C to +800°C, and strong chemical stability. Its fine crystalline structure, including mica, helps stop microcracks and withstand thermal shock. With a low thermal expansion rate, it stays dimensionally stable under harsh thermal cycles, ideal for vacuum systems and precision seals. It can be machined with standard metal tools without molds or sintering, reducing lead times and costs. Widely used in aerospace, medical, scientific, and electronic vacuum systems, Macor offers a smart alternative to PTFE, alumina, or boron nitride for complex or thin-walled parts.

Macor Machinable Glass Ceramic Properties
Macor Machinable Glass Ceramic Material Machining
Macor is one of the rare ceramics that can be machined using standard metalworking tools without requiring post-sintering processes. This makes it especially useful for prototyping and custom part production with tight tolerances. However, understanding its machining behavior is key to achieving clean, precise results.
- Standard Tool Compatibility: Macor can be drilled, milled, turned, and tapped using regular carbide or high-speed steel tools, eliminating the need for diamond tooling.
- No Plastic Deformation: Unlike metals or plastics, Macor does not deform before breaking. Operators must prevent stress concentrations to avoid edge chipping or cracking.
- Machining Precision: Surface finishes up to 0.5 µm and tolerances as tight as ±0.005 mm are achievable with careful planning and skilled handling.
- Dry Machining Preferred: Coolants are generally not required. Dry machining helps prevent contamination and simplifies cleanup in high-purity applications.
- Practice Recommended: Due to Macor’s unique cutting behavior, it’s recommended to practice machining techniques on scrap material before processing final components.
Macor Machinable Glass Ceramic Packaging
Macor machinable glass ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of the products in their original condition.
