The objective of this work is to compare the static and dynamic properties between aluminum and magnesium in a complex and functional geometry. A series of comparative tests were conducted on two geometrically-identical automotive oil pans, one produced from A380 aluminum – pulled directly from its high-volume production line – and a second produced in a casting trial using Dead Sea Magnesium's MRI 153M creep-resistant magnesium alloy. Stiffness and flexural modes were determined using holographic laser interferometry. Natural frequencies, modal behavior, and damping ratios were analyzed via hammer-impact excitations. The creep behavior of the MRI 153M alloy was compared to A380 via ultrasonic measurement of the bolt load retention (BLR) on the sealing face of the oil pans that were installed on two road test vehicles
