Vacuum Furnace Brazing. Vacuum furnace brazing is used for various metal joining processes. It takes place in a water cooled chamber that is evacuated below atmospheric pressure. Assemblies that are processed in a vacuum are bright and shiny clean. The vacuum atmosphere prevents the oxidation of parts.
Vacuum brazing furnace is principally adopted in Al brazing, Cu brazing and stainless-steel brazing of aerospace devices, vehicle components, electronic communicating devices, home appliances, heat exchanger and various heat radiators.
The vacuum aluminum brazing process is usually a relatively short cycle due to the fast pumping and heating characteristics of the furnace, the excellent temperature uniformity at soak temperatures, and the high thermal conductivity of the aluminum parts being brazed. Figure 1 shows a typical vacuum aluminum brazing cycle.

Jan 09, 2018 · Cold wall vacuum furnaces dominate the vacuum furnace industry and are available in a variety of sizes and workload configurations. In comparison to hot wall furnace designs in which the process is run inside a vacuum-tight retort, the cold wall design runs the process inside a sealed vacuum vessel.
Metal Marker Manufacturing Co., The is an industrial supplier of air heat exchanger, aluminum brazing, annealing furnace, atmosphere furnace, atmosphere furnaces, batch furnace, batch furnaces, batch oven, bell furnace, belt furnace.
That's why vacuum brazing is a less commonly employed technique than brazing with fluxes. The vacuum aluminum brazing process is usually a relatively short cycle due to the fast pumping and heating characteristics of the furnace, the excellent temperature uniformity at soak temperatures, and the high thermal conductivity of the aluminum parts being brazed.
Brazing of cold plates and heat exchangers usually takes place at approximately 1100°F (593°C) and a vacuum level between 5 to 6 Torr. However, the recipe depends in large part on the alloys, the total mass in the furnace, and the vacuum furnace being used.
Why Vacuum Brazing? Vacuum brazing is a way of producing liquid cold plates and other complex heat exchanger products, offering significant benefits over other joining technologies: • Flux free process leads to very clean parts • Highly repeatable and controllable batch process • Excellent thermal properties and the ability to deploy highly enhanced surface structures inside heat exchangers.
All of the common (and several uncommon) heat treatment processes can be run in vacuum, from annealing and brazing to sintering and tempering. Many companies that currently outsource vacuum heat-treating ask themselves if they would be better served by setting up this capability in-house.
