Macor Disc is a high-performance glass-ceramic component designed for demanding applications that require complex shapes and tight tolerances. Unlike most ceramics, Macor can be machined using standard metalworking equipment such as lathes, mills, grinders, and drills—no sintering or post-firing is required. With proper clamping and machining parameters, surface finishes as smooth as 0.5 μm and dimensional tolerances as tight as ±0.005 mm are achievable. This makes it a practical material choice for components where both thermal stability and design flexibility are critical, such as in electronics, aerospace, and vacuum systems. Heeger Materials provides high-quality Macor Disc solutions for precision-engineered applications.
