    • A 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.
    • 导体包括由包含Si为0.3-1.2质量%的Si的铝合金制成的元素线,Mg的含量使得Mg / Si重量比在0.8至1.8的范围内,剩余部分基本上包括Al和不可避免的杂质。 导体的拉伸强度为240MPa以上,断裂伸长率为10%以上,冲击吸收能量为8J / m以上,导电率为40%IACS以上。 制造方法包括通过用上述组成聚束元素线制备股线的步骤,以及对钢丝进行固溶处理,淬火和时效热处理的步骤。 固溶处理温度为500-580℃,时效热处理温度为150-220℃。固溶处理中加热是高频感应加热。
