Aluminum can be made from recycled material like pop cans, scrap aluminum, etc, which is far less expensive and energy intensive than creating new aluminum.
• Aluminum beverage cans are getting lighter. Twenty years ago, a pound of aluminum made about twenty cans. Today, the same amount of aluminum makes approximately thirty cans. The thickness of the side of an aluminum can is about the same as that of a human hair.

To lower the weight, Aluminum must be used in certain points of the structure. It's a total catch 22 situation, that cannot be solved (barring an extreme solution like mass production CF or Nuclear Powered Aluminum refineries) without taking an economic hit at some point in the circle.
