Macor Bar

Macor Bar is a machinable glass ceramic that combines high thermal resistance, excellent electrical insulation, and zero porosity. It can be precisely machined with standard metal tools without sintering, making it ideal for complex parts. With a working range from -270°C to 800°C (and up to 1000°C without load), it performs reliably in extreme environments such as vacuum systems and high-temperature assemblies. Heeger Materials (HM) provides high-quality Macor bars in custom sizes to meet technical and design requirements.

Macor Bar Properties

Macor Bar Chemical Compositions

Macor Bar Key Features

• High Thermal Stability: Withstands continuous use up to 800°C and peaks of 1000°C in non-load-bearing conditions.
• Machinable with Metal Tools: Can be milled, drilled, or turned without sintering or specialized ceramic tools.
• Excellent Electrical Insulation: Maintains dielectric properties across a wide temperature range.
• Non-Porous and Vacuum Compatible: Ideal for vacuum chambers and space applications where outgassing is critical.
• Dimensional Precision: Capable of tolerances as tight as 0.013 mm, suitable for high-accuracy assemblies.

Macor Bar Applications

• Vacuum Feedthroughs: Acts as an insulating barrier in UHV systems and electron beam equipment.
• Thermal Support Rods: Used in high-temperature furnaces and hot zones as structural elements.
• Medical and Diagnostic Equipment: Integrated into high-purity components requiring thermal or electrical isolation.
• Aerospace and Satellite Systems: Supports optical systems or electrical insulators exposed to wide temperature swings.
• Electronics Testing Fixtures: Serves as non-conductive holding jigs and probes for circuit analysis.

Macor Bar Packing 

The Macor Bar will be carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
