Abstract
Aluminum alloy wires with improved electrical conductivity and improved ultimate tensile strength are disclosed. The aluminum alloys include magnesium, silicon, and copper and are formed without a solution heat treatment. The aluminum alloy wires are useful as conductors for overhead transmission lines. Methods of making the aluminum alloy wires are further disclosed.
