Provided herein are novel, high-forming multi-layer aluminum alloy packages that include a core layer and one or more cladding layers. The alloy packages have excellent bake-hardening properties and are highly recyclable. The packages also display exceptional bendability and elongation properties. Also provided herein are novel aluminum alloy compositions for use as cladding layers. The compositions contain up to 0.6 wt. % Fe and one or more of Mn, Ni, Ti, Co, Nb, Cr, V, Zr, Hf and Ta.
