If you want to use incorrect terminology, that is fine. Stiffness has
nothing to do with plastic deformation. If you take the same size
piece of 5052, 6061, 2024, or 7075 and load them the same BEFORE
plastic deformation, you will see virtually no (less than 10%)
difference in deflection vs load.

10% in my world is hardly "virtually no"
