ZINC-ALUMINUM GALVANIZED IRON WIRE AND MANUFACTURING METHOD THEREFOR

摘要

Provided is a zinc-aluminum galvanized iron wire comprising an iron wire and a zinc-aluminum plating layer formed on the surface of the iron wire. The zinc-aluminum plating layer contains at least 3.0% and no more than 15.0% aluminum by mass, with the remainder comprising zinc and unavoidable impurities. The amount of iron in the zinc-aluminum plating layer is limited to at most 3.0% by mass. The fractal dimension of the interface between the iron wire and the zinc-aluminum plating layer, as measured by the box-counting method, is at least 1.05.
