Abstract
PURPOSE: To improve castability by a method wherein, to copper alloy with excellent strength, elasticity, strain and corrosion resistance and soldering property obtained by adding a specific amount of Ni, Zn, Al to Cu, moreover, Mn, B, Mg or the like are added.
CONSTITUTION: A spring alloy is made from Cu alloy containing Ni; 3W10%, Zn; 5W20%, Al; 0.05W3%. This alloy is excellent in strain and corrosion resistance, solderability and has good creep property as well as it's material cost low. Moreover, it's castability can be enhanced by including at least one or more of M; 0.03W0.80%, B; 0.002W0.003%, Mg; 0.01W0.3%. Moreover, if this alloy is annealed at 100W450°C, it's spring property and strength can be improved.
