Abstract
An aluminum alloy wire having excellent bending characteristics, strength, and electrically conductive characteristics, an aluminum alloy stranded wire, a covered electric wire including the above-described alloy wire or stranded wire, and a wire harness including the covered electric wire are provided. The aluminum alloy wire contains not less than 0.1% and not more than 1.5% by mass of Mg, not less than 0.03% and not more than 2.0% of Si, not less than 0.05% and not more than 0.5% of Cu, and a remainder including Al and an impurity, satisfies 0.8≦Mg/Si ratio by mass ≦3.5, has an electrical conductivity from 35% IACS to 58% IACS, a tensile strength from 150 MPa to 400 MPa, and an elongation not less than 2%. The aluminum alloy wire is manufactured through the steps of casting→rolling→wiredrawing→solution heat treatment.
