Abstract
The ductility margins of a grade 5182 aluminum–magnesium alloy, which is traditionally used in the automotive industry, and a 1565ch aluminum–magnesium alloy having a higher magnesium content and microalloyed with zirconium are analyzed and compared. The mechanical properties, their anisotropy, and the microstructures of the alloys in the annealed state are studied, and forming limit and limiting stress diagrams are plotted. The stamping of a typical automobile-body part, namely, an inner hood panel, is simulated by the finite element method. The 1565ch alloy is found to have the ductility that is high enough for an automobile-body sheet: its ductility is comparable with that of the grade 5182 alloy and even slightly exceeds it in the uniaxial tension zone.
