Precision Ceramic to Metal Assemblies for Demanding Applications

Morgan Technical Ceramics has a long history in joining ceramic and metal to create high-performance engineered components. Our teams work with our customers to design brazed assemblies to take advantage of the unique properties of each material and combining them to produce a component with a higher performance than one made from either material on its own.

Ceramic to Metal Assembly Properties

• High joint strength – hermeticity able to maintain ultra-high levels of vacuum
• Thermal resistant to withstand elevated temperatures in harsh environments
• Excellent mechanical and electrical insulation properties designed to suit the application
• Joint integrity able to withstand high stresses
  
  

Ceramic to Metal Assembly Materials

• Alumina materials – AL-300^®, Sintox™ FF and Deranox™ 995, A950, AL-998^®, AL-500^®, synthetic rubies/sapphire, ZTA
• Higher performance ceramics – Yittria stabilised zirconia, ZTA, Si₃N₄, sapphire, CVD SiC, and composite materials such as C-SiC
• Both conventional brazing materials (copper, gold, silver, precious metal eutectics) for joining metallised alumina to metals and active braze alloys (ABA^®) for joining bare alumina to metals that satisfy biocompatibility requirements
• Metals - OFHC copper, stainless steels, mild steels, monel, kovar, nickel and titanium super alloys, platinum, platinum iridium, niobium, tungsten
• Glazes for contamination protection or to facilitate cleaning
  
  

Ceramic to Metal Assembly High Temperature Applications 

Ceramic components and brazed assemblies are increasingly used in aero engines operating at higher temperatures, where conventional materials are not suitable. They can be used to help improve engine efficiency and reduce gas emissions. 

We have been designing and manufacturing high voltage feedthroughs for diagnostic equipment for over 60 years. These brazed assemblies are manufactured using high purity alumina and feature a high level of cleanliness. For our medical divison and metallising areas this is achieved via dedicated clean-rooms.
