One term for an overtorquing effect is "coldflow;" or the tendency for the conductor to "ooze" over time. Copper is not exempt from this characteristic, but it less sensitive to it.
For aluminum, it's important to call for "AA-8000" conductor alloy, [99NEC§310-14] which is compounded with a small amount of iron in the recipe. Be aware that not all aluminum insulated conductors are automatically 8000 series. Type USE cable is permitted to still be formulated of “EC-1350” alloy, as may also be utility-furnished 600V URD cables.
IMO and experience, nonreversible hydraulic-compressed terminals are the only sure bet. They just take a little more planning.
