The purpose of the present invention is to provide a steel alloy for use in a water supply member, with which leaching of Pb is suppressed while the amount of Bi used is minimized so as to ensure recyclability, said steel exhibiting satisfactory mechanical properties and castability. This alloy has: an Ni content of 0.5% by mass or less; a Zn content of 12-21% by mass; an Sn content of 1.5-4.5% by mass, the total Zn and Sn content being no more than 23.5% by mass; a P content of 0.005% by mass, and a Pb content of 0.05-0.30% by mass, and a Bi content of less than 0.2% by mass, the remainder comprising Cu and unavoidable impurities. |
