Sheet Metal Question (Aluminum)?

Question

Hi,

I am just curious which type of sheet metal would be easier to roll form. 2024 T3 or 6061 T3?

I am thinking probably either .016 or .020 for the thickness.

Thanks.

Answer 1

Both Aluminum alloys are thermally hardened but 2024 T3 is softer than 6061 T3 hence the former is easier to roll. However, these alloys have relatively low fatigue limits and if bent at a very small radius, may crack. If you need an alluminum alloy that is more manageable to roll, try the strain hardened ones, the ones with an H hardening desination such as 5086 H32.
