1050 is commercially pure aluminium
It’s un alloyed and there for doesn’t have the strength the alloyed grades offer.
However it’s a very useful grade to fabricate as sheet metal. It’s extremely workable and doesn’t require heat treatment even with sharp bends.
Folded and worked into a fuel tank or panels it can be absolutely perfect. It can be strong if it’s strength is put into the fabrication design. I’ve made a couple of tanks out of 1050 and they have been very rigid constructions.
Yes it’s a workable grade of aluminium. The point of it is it’s easily formed.I agree the construction can be rigid but it will still be easily dented when compared to say 5083.
It has been a while since I messed with them to be honest but I think it is set in Amps rather than %.
You shouldn't get HF when you are welding but you will get a tingle if you touch the tungsten with the filler but it will just be normal welding current rather than the HF.
Yes you can form 5083 but usually you get one shot and tight radius’s will crack with out first heat treatment.that makes sense...it would have been the tungsten touching the filler!
being easily dented isn't something I had really thought about, worth considering.
I want to get some sheet folded, then cut and shape the end like this...would 3mm 5083 be easy enough to form?

Don’t forget your bend allowance. You won’t get 125 if you bend 250 down the middle.125*125 equal
