Also provided is a bake hardenable, surface treated aluminum alloy sheet having improved formability, an elongation of at least 25%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising a bake hardenable aluminum alloy substrate containing Mg and Si in an amount of at least 0.4 wt % calculated as Mg.sub.2 Si and a Fe rich plating layer on a surface thereof in coating weight of 1 to 50 g/m.sup.2. By forming a zincate layer as an undercoat below the Fe rich plating layer, the plating adhesion is further improved. The preferred Fe rich plating layer is a Fe-Zn alloy plating layer containing 20 to 80 wt % of Zn for corrosion resistance improvement. A Fe-Zn alloy plating layer containing 30 to 40 wt % of Zn meets both formability and corrosion resistance.
