  • Clad aluminum alloy sheet for aircraft structural parts
    Patent number: 6528183
    Abstract: Clad sheet made up of a core sheet and a cladding layer on one or two core sheet surfaces. The core sheet is formed of an alloy having the composition (% by weight) Si: 0.7-1.3, Mg: 0.6-1.2, Cu: 0.5-1.1, Mn: 0.15-1.0, Zn<0.5, Fe<0.5, Zr<0.2, Cr<0.25, other elements <0.05 each and <0.15 total, the remainder aluminum. The cladding is formed of an AlZn alloy having a thickness of between 1 and 15% of the clad sheet thickness, having the composition (% by weight) Zn: 0.25-0.7, Fe<0.40, Si<0.40, Cu, Mn, Mg, V or Ti <0.10, other elements <0.05 each and 0.15 total.
