More superplastic forming.
Aluminum is a very cool material that exhibits "superplastic" forming characteristics at temperature. The superplastic temperature window is quite large. In the superplastic range aluminum stretches many times more than it will do while cold. Titanium also possesses superlastic forming characteristics. Many parts in the Aerospace industry (especially titanium parts) are made this way.
2004 is another aluminum superplastic alloy. It is used for high strength parts.
I love manufacturing!
