<p>PROBLEM TO BE SOLVED: To provide a steel core aluminum twisted wire having suppressed sag by utilizing an inside clearance.SOLUTION: There is provided a steel core aluminum twisted wire comprising: a steel core part 1; and an aluminum layer 3 provided at the outer circumference of the steel core part such that a clearance 2 is formed between the steel core part and the aluminum layer itself, and the steel core part comprises zinc-aluminum alloy plating layers 1p in which the mass ratio of aluminum lies in the range of 3% or more and less than 7% at the outer circumferential face. The steel core part is formed by twisting a plurality of steel wires 1w each other, and the zinc-aluminum alloy plating layers are applied at the respective surfaces of the steel wire.</p> |
