Abstract
Recrystallization of an aluminium alloy wire material is suppressed while a heat resistance of the same is improved. In a wire material made of an aluminium alloy, an aluminium alloy wire material is provided, the aluminium alloy containing Zr of 0.2 to 1.0 mass %, Co of 0.1 to 1.0 mass % and remainders that are aluminium and unavoidable impurities, and the aluminium alloy wire material having a tensile strength at a room temperature that is equal to or higher than 170 MPa, an elongation that is equal to or higher than 10%, and a stress at time of tensile deformation at a strain speed of 10−5/sec under a temperature condition of 250° C. that is equal to or higher than 40 MPa.
