You want the soft stuff that comes in rolls.  Be aware that it rapidly
work-hardens when you bend it, a second bend or trying to straighten will
be much more difficult.  If necessary you can anneal it by heating it red
hot and quenching it in water (opposite effect from steel where that would
tend to harden it).

Soft is more expensive because the working involved in making the tube
means it comes out hard.
