Morgan Technical Ceramics (MTC) recently announced that its Wesgo Metals site in Hayward, Calif., offers custom brazing services, including active metal brazing, a process that allows metal to be bonded directly to ceramic without metallization. Active metal brazing reportedly eliminates several steps in the joining process and can create an extremely strong, hermetic seal. MTC uses active metal braze alloys that can meet a range of service conditions, facilitating the joining of materials and components that could never before be accomplished. The process is especially beneficial in medical, aerospace and oil exploration applications.

MTC has developed several braze alloy compositions that will directly bond ceramic to metal or other materials, including graphite and diamond. Applications include brazing industrial diamonds onto ceramics or metal components for heat spreaders or ceramic windows, as well as brazing graphite to substrates such as titanium for incredibly stable ion traps. Alloy compositions vary and include those designed for use in a variety of settings, from very low temperatures to very high-temperature applications.

“MTC has been perfecting active metal brazing for the past two decades, which adds to available material brazing options and facilitates cost-effective one-step joining,” said Tom Sandin, product manager for Wesgo Metals. “We also develop our own brazing alloys, making us unique in the industry. Some of the newer applications, including brazing metal to graphite used in heat exchangers for cutting-edge aerospace applications, simply would not have been possible if the components had to be metalized first to facilitate brazing.”
