In this paper we deal with Cu-Ni-Si alloy to obtain an excellent anti-corrosive thin plate spring for communication apparatus. and describe the results of the experiment on the effects of sold working and precipitation hardening on mechanical properties and anti-corrosion, we conclude from the experiment described above that. (1) There is increase in the tensile strength. yield strength. spring limit, Vicker's hardness, fatigue strength and elongation of Cu-Ni-Si alloy, as the result of 500〜600℃ Precipitation treatment. They present more excellent results than in Nickel Silver alloy. There is no change presented in Young's modulus after the heat treatment. (2) Copper-Nickel-Silicon alloy develops no stress corrosion cracking, differing from Nickel-Silver and Brass. and its anti-corrossivity is for better.
