Abstract
A method of manufacturing a closure assembly for a vehicle includes trimming an outer panel to define a first edge and trimming an inner panel to define a second edge, wherein the outer panel is formed from an aluminum alloy material and the inner panel is formed from a magnesium alloy material. The method further includes chemically shaping the second edge to define a substantially rounded edge surface having a radius, positioning the inner panel adjacent the outer panel such that the first edge extends beyond the substantially rounded edge surface, and bending the first edge of the outer panel around the substantially rounded edge surface of the inner panel to form a hem connection that secures the inner panel relative to the outer panel. A closure assembly is also disclosed.
