A third factor to be considered is that formability of a specific aluminium alloy plate can be found in the percentage of elongation and the difference between yield strength and ultimate tensile strength.it is quite obvious that the best series for forming, and thus for bending, are series 3xxx aluminium plate, 5xxx aluminium plate, and in some cases 6xxx aluminium plate. Series 2xxx and 7xxx are not to be considered and thus should be avoided due to being extremely strong. They are difficult to form in any way.
