Abstract: A zinc alloy for sacrificial anode which has the same level of electrochemical properties as a conventional Zn-Cd sacrificial anode even without containing Cd that is a harmful substance is provided. A zinc alloy for sacrificial anode comprises Bi, Zn, and impurities. The zinc alloy for sacrificial anode comprises 0.05 to 0.3 wt.% of Bi, and the balance of Zn and impurities. A zinc alloy for sacrificial anode comprises Bi, Zn, at least one selected from Al and Mg, and impurities. The zinc alloy for sacrificial anode comprises 0.05 to 0.3 wt.% of Bi, 0.05 to 0.2 wt.% of Al, and the balance of Zn and impurities. The zinc alloy for sacrificial anode comprises 0.05 to 0.3 wt.% of Bi, 0.05 to 0.2 wt.% of Mg, and the balance of Zn and impurities. The zinc alloy for sacrificial anode comprises 0.05 to 0.3 wt.% of Bi, 0.05 to 0.2 wt.% of Al, 0.05 to 0.2 wt.% of Mg, and the balance of Zn and impurities.
