Which aluminum alloy would be a better choice for automobile sheet metal, considering this material will need to be formable into complex shapes, and may need to absorb the energy of a crash (AL 2024, 6061,7075)

Aluminum alloy 7075 is best suitable for automobile sheet metal.

Explanation:

Aluminum alloy 7075 is best suitable for automobile sheet metal. This alloy is also known as ultra super duraluminium.

The properties of aluminum alloy 7075 are as follows

1. The damping and form ability of this alloy is high.

2. It have high strength along all other alloy of aluminium.

3. Ultra super duraluminium have Zn is the main alloying element.

4. It have desirable yield strength for making sheet metal of automobile body.

So

Aluminum alloy 7075 is best suitable for automobile sheet metal.
