Actually, aluminum wiring has less resistance than copper... if you go by weight! That's why high voltage cabling is aluminum. Copper will sag too much because it weighs so much, same with silver. Aluminum is like 3x lighter but 2x more resistance (those are gross approximations) so there is less sag of the wires when stretched out over long distances.
