I think you are confusing large tube diameter aluminum bicycle
frame stiffness vs small tube steel bicycle
frame stiffness with the overall stiffness of the materials. If all diameters and thicknesses of the tubing is the same, the steel tubing will be stiffer. Given that a handlebar is a fixed diameter...whether in steel or aluminum...the steel handlebars are going to be stiffer than the aluminum ones by a factor of a little over 2.
It will also be around 3 times heavier.
