Vacuum Brazing Processes

Vacuum brazing is a material joining technique that offers significant advantages; it is extremely clean, and has superior, flux-free braze joints of high integrity and strength. Temperature uniformity is maintained on the work piece when heating in a vacuum, greatly reducing residual stresses due to slow heating and cooling cycles. This significantly improve the thermal and mechanical properties of the material, providing unique heat treatment capabilities. One such capability is heat-treating or age-hardening the work piece while performing a metal-joining process, all in a single furnace thermal cycle. NATIONAL HEAT TREAT has 2 furnaces with this capability.
