Clad Aluminum Brazing Sheet

This thin layer usually makes up 5 to 10 of the total thickness of the brazing sheet.

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. Navard is the only company in iran that is capable of manufacturing aluminium brazing sheet. 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. Brazing sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum silicon al si alloy.

At brazing temperature silicon from the cladding will to some extent diffuse. It melts and flows during the brazing process to provide upon cooling a metallic bond between the components. Vacuum brazing has become an important technique for joining com plex aluminum constructions e g auto motive radiators.
