ABSTRACT:
Copper alloys are disclosed which contain nickel and tin and Fe, Zn, Mn, Zr, Nb, Cr, Al, or Mg in amounts within specified limits. When cold worked and aged according to a critical schedule these alloys develop a predominantly spinodal structure which renders them strong as well as ductile. The disclosed alloys are useful, for example, in the manufacture of components of electrical apparatus such as springs, connectors and relay elements.
