I see you aren’t trying to bend them but thought I’d bore you a bit - Bending aluminium is fine in specific grades (5083/6063/6082 for plate / tubular materials), however it needs to be the correct temper. The condition ‘T’ is crucial, a T4 will be ok where as a ‘T6’ can be problematic. Also ‘O’ temper is suitable for bending. In short, the bars have already been formed in the factory and likely treated/tempered afterwards so it won’t be a good idea to try it.
