Abstract: A corrosion resistant strip is disclosed. The strip comprises a core, and an interlayer adapted to be located between the core and an optional Al—Si based clad. The interlayer has a composition essentially consisting of (in percentages by weight): Si?0.9%, Fe?0.7%, Cu?0.5%, Mn 0.5-1.8%, Mg?0.7%, Zn?4.0%, Ni?1.5%, elements selected from group IVb, Vb, and/or VIb of the periodic table ?0.3% each and ?0.5% in total ?0.05 wt % each and ?0.15% in total, of unavoidable impurity elements, balance Al. The core is more noble than the interlayer after brazing. The interlayer exhibits a volume fraction of a texture component of at least 30%.

Abstract: A method of producing an aluminium alloy brazing sheet for the manufacturing of light brazed assemblies, wherein said brazing sheet has good formability, combined with a low susceptibility to core penetration in the end annealed as-produced condition after stretching, forming and/or shaping and brazing are disclosed. Assemblies made according to the method are also disclosed.

Abstract: Disclosed is a process for producing an Al—Mn alloy sheet with improved liquid film migration resistance when used as core alloy in brazing sheet, including the steps of: casting an ingot having a composition comprising (in weight percent): 0.5<Mn?1.7, 0.06<Cu?1.5, Si?1.3, Mg?0.25, Ti<0.2, Zn?2.0, Fe?0.5, at least one element of the group of elements of 0.05<Zr?0.25 and 0.05<Cr?0.25; other elements<0.05 each and total<0.20, balance Al; homogenisation and preheat; hot rolling; cold rolling (including intermediate anneals whenever required), and wherein the homogenisation temperature is at least 450° C. for a duration of at least 1 hour followed by an air cooling at a rate of at least 20° C./h and wherein the pre-heat temperature is at least 400° C. for at least 0.5 hour.
