I can't tell what that is exactly. Maybe the clear coat peeling. It's hard to really know. The aluminum parts on the car are the doors, hood, and rear hatch. Everything other panel is steel or plastic. I think that's part of the hatch, so it's aluminum. Maybe something happened with the previous owner.
