both questions I can answer with yes!
1. Yes soft aluminum is possible, thickness could be important. 50 µm is maybe hard to catch but possible. 100 µm and higher should be no problem!
2. Yes it is possible, but not in the maximum machine width! In the range of tension which is possible from the machine it is possible, even higher! If you want send us your material information (alloy, width, etc.) and we calculate!
