Abstract

Provided are an aluminum alloy wire (2) having excellent flexing characteristics, strength, and electrical conductivity, a twisted aluminum alloy wire, a covered electric wire (10) including the alloy wire or twisted wire, a wire harness including the covered electric wire (10), a process for producing the aluminum alloy wire, and a process for producing the covered electric wire (10). The aluminum alloy wire (2) contains, in mass%, 0.1-1.5% Mg, 0.03-2.0% Si, and 0.05-0.5% Cu, the remainder comprising Al and impurities. The aluminum alloy wire (2) satisfies the relationship 0.8=Mg / Si (by mass)=3.5, and has a conductivity of 35-58 %IACS, a tensile strength of 150-400 MPa, and an elongation of 2% or more. This aluminum alloy wire (2) is produced through the steps of casting, rolling, wire drawing, and solution heat treatment in this order. By using the specific composition and by conducting a solution heat treatment after wire drawing to sufficiently bring the additional elements into a solid-solution state, the aluminum alloy wire (2) having excellent flexing characteristics can be obtained.
