Zusammenfassung:	The implementation of aluminum in today's automotive body panels is an engineering problem seeking resolution of conflicting objectives including structural integrity, manufacturability and cost. This paper utilizes the results of a computer modeling technique to show the effects of differing aluminum alloy properties on body panel characteristics including: stiffness, dent resistance, oil canning, draw-die overcrown, minimum thickness, cost and weight. Minimum cost aluminum alloy selection is shown to be sensitive to panel curvature, inner panel support, yield strength and draw-die overcrown limits. Two case studies are presented comparing 1100, 3004, 5182-SSF, 2036-T4 and 6010-T6 aluminum alloys for varying design configurations of a typical automotive hood.
