Abstract
In a first aspect, the invention provides aluminum alloy comprising the following composition, all values in weight %: Si 0.25-1.5 Cu 0.3-1.5 Fe up to 0.5 Mn up to 0.1 all other elements including Mg being incidental and present (if at all) then in an amount less than or equal to 0.05 individually, and less than or equal to 0.15 in aggregate, the balance being aluminum. In a second aspect, the invention provides a composite aluminum sheet product comprising a core layer and at least one clad layer wherein the at least one clad layer is an aluminum alloy comprising the following composition, all values in weight %: Si 0.25-1.5 Cu 0.3-1.5 Fe up to 0.5 Mn up to 0.1 all other elements including Mg being incidental and present (if at all) then in an amount less than or equal to 0.05 individually, and less than or equal to 0.15 in aggregate, the balance being aluminum. In a third aspect, the invention provides a method of making a joined structure of a steel component and an aluminum component made from the alloy and/or the sheet product of the invention.
