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.

Clad aluminum brazing sheet.

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. It melts and flows during the brazing process to provide upon cooling a metallic bond between the components. Navard is the only company in iran that is capable of manufacturing aluminium brazing sheet. Brazing sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum silicon al si alloy.

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.
