Thank you,Jake BissenAluminum really has problems with the highly insulating surface oxide layer. Even if screws are used to fix connection wires after removing most of the oxidation the connections tend to become loose because aluminum flows under pressure. Pressure washers must be used. Just flexible wires fixed with tape will make poor connections. Connections using plugs or something allowing quick connection and firm contact would be better, if you want to save the time that connections with screws would take.You could have made an armor suit made of brass, for example, that is not much more difficult to work than aluminum and far easier than steel. No problems with connections with brass, and a "golden suit" would look more impressive.Antonio Carlos M. de Queiroz
I was thinking about that - brass (or copper) would work, but would potentially be a lot heavier. Steel is actually pretty good, but heavy, and it's easy to make "good enough" contacts, but you'd have the rusting problem, and Jake can't just throw his armor at his squire and say "have it all polished up by tomorrow". Stainless steel would work, but is also heavy.
The commercial shark suits that folks use as shielding chain mail are stainless steel.
This is an interesting challenge - aluminum is nice - easy to form, always clean, light weight. I suspect that if you do make wire connections with, say, screws, eventually they'll get loose as Antonio describes. And then you might not get directly shocked, but you might get burned by the sparks jumping the gap, and that would probably be more painful than the RF spark (which are notorious for doing damage but not hurting a lot - see the archives)
Some sort of compression bonding technique that can't loosen is going to be the key - I'm thinking that some sort of rivet that swages the wire into the aluminum with some residual tension to keep it from loosening. Maybe the choices of aluminum alloy might help.
