Abstract

The invention provides an aluminum alloy sheet having improved formability, an elongation of at least 30%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising an aluminum alloy substrate containing at least 4 wt% of Mg and a Fe rich plating layer on a surface thereof in a coating weight of 1 to 50 g/m2.
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 Mg2Si and a Fe rich plating layer on a surface thereof in coating weight of 1 to 50 g/m2.
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.

By further forming a layer of an inorganic compound such as alkali metal borate on the Fe plating layer, sliding frictional behavior is further improved.
The preparation of a bake hardenable, surface treated aluminum alloy sheet includes annealing at a temperature of at least 480°C before or after Fe rich plating.
