answer:It could have yes. I have worked with metal a lot over the years, specially sheet metal. and ultra thin aluminium is very easy to bend. most metals are if they are thin. aluminium is very soft, you could even bend a sheet that is say 2.5mm thick with your hands and without much effort. If this piece of metal is anywhere near a heat source, such as the batery, then the heat would make it even easier to bend.
