Hermetic Brazing of AlN Receptacle to Kovar Tube

The contract requires the hermetic brazing of aluminum nitride receptacles to Kovar tubes, rated for operation at up to 700°C, using vacuum or controlled-atmosphere furnace processes to meet aerospace-grade reliability standards. This work demands precise material compatibility, thermal expansion matching, and flawless seal integrity to ensure long-term performance under extreme thermal and mechanical stress conditions typical of space and high-temperature aerospace applications. The brazing process must eliminate porosity, prevent oxidation, and maintain dimensional stability throughout assembly to guarantee leak-tight hermeticity critical for mission-critical systems. The solicitation is issued as a subcontract under NASA Shared Services Center, with the National Aeronautics and Space Administration as the overseeing agency. The place of performance is specified as Cleveland, Ohio, with a zip code of 44135, indicating the work must be executed at or near this location. The North American Industry Classification System code 332996 classifies this as Other Fabricated Metal Product Manufacturing, underscoring the specialized nature of the fabrication process. Interested parties must submit responses by June 30, 2026, at 12:00 PM Eastern Time, following the posting date of June 26, 2026, with no set-aside designation specified, meaning any qualified vendor may compete.
