Brazed Assemblies

The Technical Ceramics business of MACOR® Machining China has the capability to produce custom alumina and metal braze assemblies, using precious and non-precious metals, from sizes below 1mm to 400mm.

Ceramic to metal brazed assemblies are manufactured providing high mechanical strength and good high voltage electrical insulation. Our brazed assemblies are hermetic, able to maintain ultra high levels of vacuum and joint integrity that is maintained at elevated temperatures in harsh environments.

Materials used in brazed assemblies include:

  • Alumina materials – Sintox FF and Deranox 995, A950, AL-300(R), AL-500(R)
  • Conventional brazing materials or Active Braze Alloys (ABA) aero
  • Metals - OFHC copper, stainless steels, mild steels, monel, nickel and titanium
  • Glazes for protection or to facilitate cleaning

Typical applications include:

  • Mass spectrometry
  • Gas detectors
  • Microscopes (TEM, SEM)
  • Particle accelerators
  • Nuclear detectors
  • High voltage feedthrough for X-ray equipment, scanners and imaging applications for medical
  • Sensors, satellite propulsion and engine management for aerospace
  • PMTs and power tubes
  • RF feedthroughs
  • Electrical feedthroughs
  • Pinch off tubes for lasers
  • Gas lasers
  • Deep sea repeaters
  • Rechargeable batteries for energy storage

We are fully certified to meet your application requirements, holding the following standards:

  • AS9100 accredited
  • NADCAP accredited for welding
  • ISO9001, ISO13485, and ISO14001 accredited

For government work, we are also ITAR registered and cyber security certified.
