I can't recall why but I believe I've read that heating and bending steel would be very different from heating and bending aluminium alloy.
Perhaps someone with actual metallurgy knowledge can confirm, but in the meantime don't do it.
Cupcakes-
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.

Would heating the bars up with a blow torch not facilitate bending them? Bend when hot.
I've done this with steel rebar so I imagine the process would be similar for an aluminium part.
Maybe just be careful to not bend it too far, I imagine that the metal would start tearing.
