Abstract: The invention relates to an age-hardenable aluminium alloy product for structural members having a chemical composition including, in wt. %: Cu about 3.6 to 6.0%, Mg about 0.15 to 1.2%, Ge about 0.15 to 1.1%, Si about 0.1 to 0.8%, Fe<0.25%, balance aluminium and normal and/or inevitable elements and impurities. Zn, Ag and/or Ni may or may not be present. A typical range for Zn is <0.3 or, in a further embodiment about 0.3 to 1.3%. A typical range for Ag is <0.1 or, in a further embodiment about 0.1 to 1.0%. Products made from this aluminium alloy product are very suitable for aerospace applications. The alloy can be processed to various product forms, e.g. sheet, thin plate, thick plate, extruded or forged products. Products made from this alloy can be used also as a cast product, ideally as die-cast product.
