Morgan Technical Ceramics is experienced in combining ceramic and metal for engineering components. Our engineers design assemblies to take advantage of the unique properties of each material and combine them to produce a component with a higher performance than one made from either material on its own.
Ceramic-to-metal brazed assemblies are manufactured to provide high mechanical strength and good electrical insulation. Our brazed assemblies are hermetic and able to maintain ultra-high levels of vacuum and joint integrity even at elevated temperatures and in harsh environments.
Ceramic to Metal Assemblies Materials
- Alumina materials – AL300®, Sintox FF and Deranox 995, A950, AL-998®, AL-300®, AL-500®, synthetic rubies/sapphire, ZTA
- Higher performance ceramics – Yittria stabilised zirconia, ZTA, Si3N4, sapphire, CVD SiC, and composite materials such as C-SiC
- Conventional brazing materials (copper, gold, silver, precious metal eutectics) for metallised alumina or active braze alloys (ABA) from a biocompatibility requirement, to an ‘above superalloy melt temperature’
- 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

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 two dedicated clean-rooms.
