Aluminum wire is still all the rage. All the high power wire you see on poles and the ones that come right to your house are aluminum. Nothing wrong with it at all. The problem with it is the connection points when aluminum oxidizes and these connections can start arcing. Use of a proper conductive grease coating these connections work great. The problem is that so many connections are made in a house it makes it pretty tough to inspect and monitor them all. Also, aluminum weighs 1/3 the weight of copper and can transmit twice as much power per lb as copper. FWIW
