Abstract

Exemplary embodiments of the invention relate to a sheet article having opposed first and second surfaces, and having a core layer, a cladding layer at the first surface of the sheet article, and optionally a cladding layer at the second surface of the sheet article. The cladding layer at the first surface is made of an aluminum alloy selected from alloys AA3104, AA3004 and modified versions of alloys AA3104 and AA3004 additionally containing 1.0 to 2.0 wt % Fe and optionally up to 1 wt % Si. The core layer is an aluminum alloy having a yield strength and/or ductility greater than the yield strength and/or ductility of the alloy of the cladding layer at the first surface. The sheet article may be used as can body stock, can end stock and tab stock.
