BRASS ALLOY EXCELLENT IN RECYCLABILITY AND CORROSION RESISTANCE, PROCESSED COMPONENT AND CONTACTING LIQUID COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a brass alloy element excellent in recyclability and corrosion resistance capable of simply being processed by securing machinability while preventing inclusion of lead and avoiding addition of Bi or Si, a processed component and a contacting liquid component.SOLUTION: There is provided a brass alloy element containing, at least Cu:58.0 to 63.0 mass%, Sn:1.0 to 2.0 mass%, Sb:0.05 to 0.29 mass%, Pb:0.3 mass% and the balance Zn with inevitable impurities, having improved stress corrosion crack resistance and machinability, and excellent in recyclability and corrosion resistance.
