Abstract:
A plated steel wire with high corrosion resistance and excellent workability, the plated steel wire being characterized in that the average composition of the plating alloy contains, in terms of weight percentage, Al: 4-20%, Mg: 0.8-5% and the remainder Zn, and in that an Feâ€”Zn alloy layer, containing Al: &lE;4%, Mg: &lE;1%, of no greater than 20 &mgr;m thickness is present at the plating-base metal interface, and the structure of the plating alloy layer on the outer side of said Feâ€”Zn alloy layer includes an ax phase composed mainly of Alâ€”Zn, a &bgr; phase comprising a Zn monophase or an Mgâ€”Zn alloy phase, and a Zn/Al/Znâ€”Mg three component eutectic phase.
