ABSTRACT:
Copper-silicon based alloys which exhibit high elastic properties and resistance to bending fatigue are disclosed. These alloys incorporate silicon in amounts ranging from 4.4 to 5.2%. Optional elements may be added to the copper-silicon alloys, but are limited in amounts such that not less than 4.4% of silicon is present in the alloy. These alloys have particular utility in spring-type electrical connection devices.
