Aluminum-based electrical wiring was first used for utility applications in the early 1900s. Use of aluminum wiring grew rapidly after World War II and it has increasingly replaced copper as the conductor of choice in utility grids. The metal has significant cost and weight advantages over copper and is now the preferred material for electricity transmission and distribution uses. AA-8000 series aluminum alloy conductors have more than 40 years of reliable field installations and have been recognized specifically by the National Electrical Code for over three decades. Aluminum electrical wiring is an increasingly popular choice for utilities and builders. The market has grown 20 percent over the past decade. (Taken from The Aluminium Association)
