Abstract

A metal sheet for a motor vehicle body outer panel, having a thickness ranging between 0.8 and 1.2 mm, containing, in wt. %, Fe 0.25-0.40 and preferably 0.25-0.35; Si 0.90-1.20 and preferably 0.95-1.10; Cu 0.10-0.25 and preferably 0.15-0.20; Mg 0.35-0.50 and preferably 0.40-0.50; Mn 0.05-0.20 and preferably 0.08-0.15; other elements<0.05 each and <0.15 in total, the rest being aluminum. The sheet has, after solution heat treatment, quenching, pre-tempering or reversion, and maturation at room temperature for 3 weeks to 6 months, an L R0.2 direction yield strength less than 160 MPa, and preferably less than 150 MPa. A yield strength>180 MPa can be obtained on the body stamping part after the paint has been cured. The sheet of the invention enables a reduction in the thickness of parts while satisfying all the other required properties.
