Aluminum Vacuum Brazing Furnace is used to brazing aluminum plate fin Heat Exchanger, aluminum plate bar coolers, aluminum radiators and more aluminum brazing products which are widely applied in cars, locomotive, truck, compressors, engineering machines, air separation equipment etc. Vacuum brazing of aluminum does not involve the use of flux so eliminates any risk of corrosion.
may cause lack of brazing. Thus aluminium furnace brazing in air finds little practical application. The most important furnace brazing methods for aluminium are brazing in vacuum and under controlled atmosphere. There is also considerably less impact on the environmental compared to open furnace brazing and salt-bath brazing.

201697Vacuum furnaces allow high quality production at a low unit cost, eliminating excessive production waste and wastage of raw materials. Regardless of the industry in question (automotive, aerospace, energy, etc.), vacuum provides the ideal brazing conditions for the production of heat exchangers made from aluminium alloy.
Furnace brazing allows the joining together of complex or simple designs involving a single joint or multiple joint assemblies. One of the most frequent types of furnace brazing aluminum is carried out within a vacuum furnace. This process is referred to as vacuum brazing.
"We have some customers that have 1,000 joints in one assembly. You put it in a vacuum furnace, and 4 hr. later it is complete." Brazing is also very good at joining different thicknesses of material as well as dissimilar materials such as metal to ceramics or steel to nickel alloys in aerospace applications.
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 Services Strong, Clean, Leak-free Joints. Fluxless vacuum brazing services from Solar Atmospheres allows you to join metals while keeping the assembly bright and clean. Unlike soldering or welding, even complex shapes can be brazed with little distortion. The vacuum brazing process is ideal for joining ferrous and non-ferrous metals:
201945PROBLEMS WITH MAGNESIUM IN A VACUUM FURNACE. Because the vacuum-furnaces that are used for aluminum-brazing are what are known as "cold-wall" vacuum furnaces, the Mg gas will condense on those cooler furnace walls, building up a layer of pure magnesium over time, which must be removed.
A number of materials are suitable for Fe 3 Al alloy vacuum brazing, including pure aluminum foil, Cu-based alloys, Ag-based alloys and Ni-based alloys. 5 When pure aluminum foil is selected as the interlayer for Fe 3 Al alloy vacuum brazing, the diffusion reaction area occurs in the joint, and the hard, brittle Fe 2 Al 5 phase will also form in this area.
Vacuum furnaces is a relatively economical method of oxide prevention and is most often used to braze materials with very stable oxides (aluminum, titanium and zirconium) that cannot be brazed in atmosphere furnaces. Vacuum brazing is also used heavily with refractory materials and other exotic alloy combinations unsuited to atmosphere furnaces
For performing Furnace Brazing-aluminum a regular flux has to be pre placed in the joints, together with the filler metal, or else heating must occur in a protective atmosphere or in vacuum. The requirement for furnace temperature accuracy is very strict, at least +5.5 °C (+10 °F). Dip Brazing-aluminum was introduced in our page on Brazing

FURNACES FOR BRAZING ALUMINIUM - HIGH PERFORMANCES AT LOW TEMPERATURES Our vaccum furnaces for brazing aluminium. The vacuum braze welding process of aluminium is simple if some fundamental aspects of the process are known such as the choice of suitable materials, a correct procedure and the features of the furnace.
Vacuum Aluminium Brazing (VAB) is utilized to perform fluxless brazing of aluminum components in a high vacuum environment. The process demands tight control of temperature uniformity together with low vacuum leak rates and high repeatability. VAB will provide a component with very clean, high quality, high strength brazed joints.
