Abstract

An aluminum alloy material suitable for the manufacture of automotive body panels comprising: Si 0.6 to 1.2 wt %, Mg 0.7 to 1.3 wt %, Zn 0.25 to 0.8 wt %, Cu 0.02 to 0.20 wt %, Mn 0.01 to 0.25 wt %, Zr 0.01 to 0.20 wt %, with the balance being Al and incidental elements, based on the total weight of the aluminum alloy material. The aluminum alloy material satisfies the inequation of: 2.30 wt %≤(Si+Mg+Zn+2Cu) wt %≤3.20 wt %.
