Clad Aluminum Brazing Sheet

Aluminum brazing sheet 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.

Vacuum brazing has become an important technique for joining com plex aluminum constructions e g auto motive radiators. 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. This thin layer usually makes up 5 to 10 of the total thickness of the brazing sheet. At brazing temperature silicon from the cladding will to some extent diffuse.

Navard is the only company in iran that is capable of manufacturing aluminium brazing sheet. It melts and flows during the brazing process to provide upon cooling a metallic bond between the components. Brazing sheet is a composite material typically consisting of a core alloy and one or more liner alloy that are metallurgically bonded clad to the core alloy.
