Abstract

PURPOSE: To obtain a Cu alloy with superior high-duty elasticity and corrosion resistance by adding a specific amount of Al, Fe and Ni to a Cu-Zn alloy.
CONSTITUTION: To Cu are added 15.0W30.0% Zn, 2.0W4.0%Al, 0.1W1.0% Fe and 0.1W2.0% Ni (Fe+Ni≥0.4%). An ingot of this Cu alloy is hot rolled at about 850°C to form a 11mm thick plate, and scale on the plate surface is removed by planing. The plate is then subjected to cold rolling to 3.0mm thickness, annealing at 520°C for 60min, washing, cold rolling to 1.2mm thickness, annealing at 525°C for 60min, washing and cold rolling to 0.6mm final thickness, The resulting Cu alloy has very superior high-duty elasticity and corrosion resistance, and it is suitable for use as a material for electrical appliance parts such as a switch, a terminal and a connector.
