Clad Aluminum Brazing Sheet

Main application for aluminum 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. It melts and flows during the brazing process to provide upon cooling a metallic bond between the components.

This thin layer usually makes up 5 to 10 of the total thickness of the brazing sheet. Brazing sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum silicon al si alloy. 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.
