Abstract (en)
[origin: WO9721508A1] A method for making aluminium alloy strips having high mechanical strength and good formability, comprising (a) providing an alloy containing 0.5-13 wt.% of Si, 0-2 wt.% of Mg and/or 0-1 wt.% of Mn and/or 0-2 wt.% of Cu and/or 0-2 wt.% of Fe, the other elements being present in an amount of 0.5 wt.% each and 2 % in total; (b) continuously casting the alloy between two cooled rolls to produce a cast strip with a thickness of 0.1-5 mm, the force applied to the rolls being maintained, in a specific force-thickness diagram, below a straight line AB and preferably below a straight line A'B', where the co-ordinates of A, B, A' and B' are A: 1.5 mm, 750 t/m; B: 5 mm, 500 t/m; A': 1.5 mm, 700 t/m; and B': 5 mm, 300 t/m; and (c) optionally rolling the strip. Such strips may be used, e.g., for making motor vehicle bodywork components.
