    Abstract: The present invention provides a method for producing AlMn strip or sheet for making components by brazing, as well as the products obtained by said method. In particular this method is related to fin materials of thin gauge used in heat exchangers. Rolling slabs are produced from a melt which contains o C to control the number and size of dispersoid particles, and the preheated rolling slab is hot rolled into a hot strip. The strip is thereafter cold rolled into a strip with a total reduction of at least 90%, and the cold rolled strip is heat treated to obtain a 0.2% proof stress value that is 50 –90% of its proof stress value in the as cold rolled condition to a proof stress value in the range between 100 and 200 MPa. The strip may alternatively be produced by twin-roll strip casting. The composition of the melt tailors the microstructure development during the complete processing to give the desired post braze properties and performance during brazing in combination with adequate delivery properties of the strip. In particular the high post braze strength combined with a good sagging resistance and low susceptibility to liquid core penetration during brazing, also for thin strip and slow brazing cycles, as well as a relatively good formability in the delivery condition prior to fin forming.

    Abstract: The invention relates to a method for producing a heat exchanger header tank comprising the steps of providing a tube having a core made from a AA3XXX-aluminium alloy; optionally pre-heating the tube; inserting the tube into a forming tool having a forming cavity with the shape of the final header tank; plugging the ends of the tube; internally pressurising the tube by the use of a gas so as to make it conform to the shape of the tool cavity, thus obtaining the final header tank; removing the header tank from the tool; and cooling the header tank. This method allows an efficient production of header tanks of irregular shapes made of AA3XXX aluminium alloy. The invention also relates to a method for producing a heat exchanger, where the header tank is connected to a plurality of tubes and corrugated fins inserted between the tubes, followed by brazing of the fins to the tubes.
