Hot-dip galvanizing bath and galvanized iron article

A hot-dip galvanizing bath contains 0.005 to 0.2 mass % of Cu. In this case, the hot-dip galvanizing bath preferably further contains 0.001 to 0.1 mass % of Al. A Zn-Bi galvanizing bath preferably contains 0.05 to 5.0 mass % of Bi, and a Zn-Pb galvanizing bath preferably contains 0.05 to 3.0 mass %...

Beschreibung
Zusammenfassung:	A hot-dip galvanizing bath contains 0.005 to 0.2 mass % of Cu. In this case, the hot-dip galvanizing bath preferably further contains 0.001 to 0.1 mass % of Al. A Zn-Bi galvanizing bath preferably contains 0.05 to 5.0 mass % of Bi, and a Zn-Pb galvanizing bath preferably contains 0.05 to 3.0 mass % of Pb. An iron article galvanized using the above hot-dip galvanizing bath exhibits an excellent appearance and corrosion resistance.
