Apr 24, 2011 Brazing aluminum is a quick and inexpensive option for repairing leaks, cracks, or holes in aluminum and is often found in air-conditioning repairs. When compared to welding equipment, aluminum brazing equipment is inexpensive, portable, and does not require high amounts of voltage.
The standard brazing process involves joining of components with a brazing alloy, typically an aluminium-silicon filler alloy. Al-Si brazing aluminum alloys have melting ranges from 577C to 610C, which is appreciably lower than the melting point range of the base Brazing aluminium alloy used for heat exchangers (630C 660C).
Aluminum brazing sheet is produced by providing a composite assembly comprising an ingot of aluminum alloy and a layer of an aluminum brazing alloy on at least one side of the ingot. Provided on both sides of the composite assembly is a second layer of aluminum alloy substantially free of eutectic or elemental silicon. The composite assembly and the second layer are hot bonded and formed into ...

A: Aluminum dip brazing uses a salt bath flux which breaks down metal oxides and enables a filler metal to diffuse in to the base metal. Aluminum vacuum brazing uses a clean vacuum environment without flux. There are some cases where the design of the part dictates which process should be used.
Cladding aluminum strip sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum-silicon (Al-Si) alloy. This thin layer, usually makes up 5 % to 15 % of the total thickness of the brazing sheet. It melts and flows during the brazing process, to provide upon cooling a metallic bond between the components.
