Vacuum brazing has become an important technique for joining com plex aluminum constructions e g auto motive radiators.
Clad aluminum brazing sheet.
It melts and flows during the brazing process to provide upon cooling a metallic bond between the components.
Main application for aluminum brazing sheet.
At brazing temperature silicon from the cladding will to some extent diffuse.
Aluminum brazing sheets for brazed automobile heat exchangers cladding an aluminum silicon alloy with a brazing sheet provides an aluminum alloy that has the thin walls necessary for use in automobile heat exchangers as well as such desirable characteristics as high strength corrosion resistance and formability.
This thin layer usually makes up 5 to 10 of the total thickness of the brazing sheet.
The radiator parts are manufactured from braze clad materials with aa 3003 or aa 6063 as the core alloy and aa 4004 as the cladding.
