Default Straightening 7075 T6 alloy

If 7075 T6 alloy is bent say a few mm, nothing major. and you straighten it, my ? is will it be weaker and more likely to bend in that same spot again then if it was never bent?

the part im talking about is a 4mm thick shock tower

Aluminium does the opposite of what steel does when bent. It becomes harder and harder the more you bend it, eventually it will just crack. If youre unlucky it might even crack when you try to straighten it, might be worth a try though.

Once 7 series Aluminum is bent, its compromised. No bending it back. 6 series you COULD get away with it, but not 7 series.

If you do this, heat will be your very good friend.. Just don't go over board with it, but don't skipm too much either.. Think propane torch, for sweating copper pipe. Keep the heat moving until you're ready to bend..
