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.
Claims5
Cold worked and aged spinodal copper alloys consisting essentially of nickel in an amount of from 2-20%, tin in an amount of from 2-8%, an additional element selected from the group consisting of Fe in an amount of from 2 to 15%, Zn in an amount of from 2 to 10%, and Mn in an amount of from 2 to 15%, and remainder copper.
Cold-worked and aged spinodal copper alloys consisting essentially of nickel in an amount of from 2-20%, tin in an amount of from 2-8%, at least one additional element selected from the group consisting of Zr in an amount of from 0.05-0.2%, Nb in an amount of from 0.1-0.3%, Cr in an amount of from 0.5-1%, Al in an amount of from 0.5-1.5%, and Mg in an amount of from 0.5-1%, and remainder copper.
