Abstract

There is provided an aluminum-alloy material having sufficient electric conductivity and tensile strength as a wiring material and excellent in wire-drawing property, and an electric wire or cable using the same. An electric wire or cable includes an aluminum-alloy strand formed of an aluminum-alloy including Fe: 0.1% by mass or more to less than 1.0% by mass, Zr: 0 to 0.08% by mass, Si: 0.02 to 2.8% by mass, at least one of Cu: 0.05 to 0.63% by mass and Mg: 0.04 to 0.45% by mass, and the remainder being aluminum and unavoidable impurities.

Claims

1. A method for producing an aluminum-alloy strand from an aluminum-alloy comprising:

Fe;

0.1% by mass or more to less than 1.0% by mass;

Zr;

0 to 0.08% by mass;

Si;

0.02 to 2.8% by mass;

at least one of Cu;

0.05 to 0.63% by mass and Mg;

0.04 to 0.45% by mass; and

the remainder being aluminum and unavoidable impurities,

the method comprising the steps of;

(1) forming a wire rod using the aluminum-alloy;

(2) wire-drawing the wire rod without a thermal treatment until becoming a desired final wire diameter; and

(3) continuously annealing or batch-wise annealing the wire rod which has been wire-drawn.
