High temperature vacuum brazing furnace
Description :
Vacuum brazing is carried out in the absence of air, using a specialized furnace, and delivers significant advantages: extremely clean, flux-free braze joints of high integrity and superior strength. Improved temperature uniformity when heating in a vacuum, and lower residual stresses due to slow heating and cooling cycle, results in significantly improved thermal and mechanical properties of the material. Other benefits of vacuum brazing include heat treating or age hardening of the work piece as part of the metal-joining process, all in a single furnace cycle. Like conventional brazing, vacuum brazing is easily adapted to mass production.
-No oxidation, no weld flux, no pollution, no air hole;
-Low temperature brazing, high temperature brazing, continuous brazing;
-It works on Titanium (Ti), Zirconium (Zr), Niobium ( Nb), Molybdenum (Mo) refractory metal alloys and dissimilar metals too;
-High automation, easy operation, easy maintain.
