Aluminum Wire
Aluminum wire is inferior to copper. That is because aluminum expands and contracts and that makes the connections come undone. This fact, alone, can lead to fires. It also corrodes and, over time, that will increase resistance. It is also stiffer and more difficult to work with. Aluminum has a lower melting point than copper. That means you must use a larger aluminum wire against the same copper wire.
Aluminum wiring was mostly used in the late sixties and early seventies. It was used because the price of copper rose up and it was more economical.
One of the best advantages to aluminum is that it is approximately 50% lighter than copper. This makes it ideal for running large wires on power poles. It has been the standard for utility companies and power grids.
