I have a bit of a tough time with that one. Aluminum is used for household wiring. I think that it is less used nowadays for reasons I am not certain of but it is nonetheless a good conductor.

Carbon fibre is also an excellent conductor as I remember from my hang gliding days there was a guy outside Salt Lake City at a place called "Point Of The Mountain Utah" (I get excited just remembering the excellent flying conditions there) who accidentally managed to sink out and land on some powerlines which were on the perimeter of the "South side".

His carbon fibre glider burned and cooked for quite awhile and knocked out the power to wherever it was going.

Fortunately the webbing which was used to suspend him was conconductive and he managed to only suffer injuries from the fall from the wires.

It was actually kind of bizarre that he was that low in the area of the wires.
