What do you mean by "harder?" Without actually looking it up, I thought the big difference between iron and aluminum, other than weight and related thermodynamic properties, was plasticity characteristics. Specifically, aluminum would be less prone to bending or deformation, but when it does it's a catastrophic breakage rather than mere bending. Not sure how that effects the dynamics in this situation, though.
