Abstract
A conductor excellent in tensile strength, breaking elongation, impact resistance, electrical conductivity, and fatigue resistance, and a production method thereof. The conductor includes elemental wires made from an aluminum alloy containing Si whose content is 0.3-1.2 mass %, Mg whose content makes an Mg/Si weight ratio in a range from 0.8 to 1.8, and a remainder essentially including Al and an unavoidable impurity. The conductor has tensile strength of 240 MPa or more, breaking elongation of 10% or more, impact absorption energy of 8 J/m or more, and electrical conductivity of 40% IACS or more. The production method includes the step of preparing a strand by bunching elemental wires with the above composition, and the step of subjecting the wire to solution treatment, quenching, and aging heat treatment. Solution treatment temperature is 500-580° C., and aging heat treatment temperature is 150-220° C. Heating in solution treatment is high frequency induction heating.
