Vacuum Brazing Vacuum brazing is a particular type of furnace brazing, where vacuum is created in the furnace for carrying out brazing process. Unlike other heat treating furnaces which uses protective gas atmosphere, vacuum furnace make use of comparatively low atmospheric pressures.

Heat exchangers or condensers with a heat transfer surface area greater than 0,05 m 2, and less than 30 m 2; and tubes, plates, coils or blocks (cores) designed for such heat exchangers or condensers, where all surfaces that come in direct contact with the fluid(s) are made from any of the following materials:
The graphite die is equipped with double-acting graphite rams, see figure 1.9. The powder mixture is cold pressed and then inserted into the hot-pressing apparatus. The graphite die is heated by placing a potential across copper plates and allowing the current flow to heat resistively the die.
Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacrificial coating" corroding before the substrate material. 2" diameter More is a standard form for many plating applications.
For more complex alloys, vacuum furnaces are often the best option for heat treating and brazing. As their name suggests, vacuum furnaces evacuate all atmosphere in order to prevent unwanted chemical reactions from occurring during the heat treating or brazing process and to allow metallurgists to design in-depth thermal processes for complex alloys.
Heat treatment and Brazing furnaces Wide range of batch and semi-continuous production with process support for different applications such as Hardening and Tempering, Annealing, Sintering, Stress Relieving and Brazing.

In this article, we present an introduction to the general points of aluminum brazing. A brief description of two of the three most-used processes is also discussed:brazing in an inert-atmosphere furnace with flux (it is necessary to purge by vacuum at the beginning of the cycle) and brazing in a vacuum furnace without flux.

Heat shields consist of multiple layers of refractory metal sheets. Heating elements and heat shields are easily accessible for inspection and maintenance. The entire inside of the vacuum chamber is designed to conform to the best high vacuum practices with particular attention given to surface finishes and choices of construction materials.
Apr 25, 2014 · To process these types of materials without any discoloration, an oil diffusion pump is added to the pumping system. The diffusion pump will remove even more air from the heat treating chamber to provide a "super-clean" environment for processing. Diffusion pumped systems are also preferred for vacuum brazing furnaces.
Vacuum heat treatment furnace with high thermal efficiency, that is, rapidly heating and cooling, can realize remove phosphorus crumbs on the surface of the workpiece, and has the function of degreasing, degassing, no oxidation, no decarburization and no carburizing, so as to achieve the surface brightness purification effect.
