Titanium is stiffer than aluminium, weight for weight. However, the lower density of aluminium means that to achieve the same strength the cross section is wider, so the structure as a whole is stiffer. This is why aluminium bicycles have tubes with thicker wall sections (and thus thicker tube diameters) than steel or titanium bicycles.

Stiffness is not the same as strength.
