Different Al-based alloys were evaluated as materials for cladding on a high-strength Al-Zn-Mg-Cu-Ni-Zr alloy with high-strain rate superplasticity. Clad sheets were fabricated by hot-roll bonding. Superplastic behaviour, mechanical properties at room temperature and corrosion properties of clad sheets were studied. The microstructure analysis and tensile results revealed that bonding was acceptable in the samples with cladding materials. The research revealed that the Al-Zn-Ca alloy provided good corrosion protection, superplasticity and a low decrease in the mechanical properties of cladded sheets.
