The high-strength and high-elasticity copper alloys have high strength and high elasticity and are mainly used for various elastic components carrying current and elastic elements for precision instruments. Based on the achievements in the field of high-strength and high-elasticity copper alloys in recent years,this paper introduced four typical elastic copper alloys including Cu-Be,Cu-Ni-Mn,Cu-Ni-Si and Cu-Ni-Sn. The research,production and application progress of the four types of copper alloys have been ...
