Conventionally, inexpensive brass, nickel silver, and silver bronze, which have excellent spring properties, have been used as spring materials for switches, connectors, etc. However, brass has the disadvantage of poor spring properties and stress corrosion cracking. However, phosphor bronze and nickel silver are expensive and have poor electrical conductivity. Therefore, the present applicant first developed an alloy that has excellent spring properties, is inexpensive, and has corrosion resistance. (Patent No. 54-167517) Regarding this alloy, it was partially stated in the application specification that the strength and springiness were improved by applying heat treatment after final cold rolling.
The present invention shows that in order to maximize the excellent properties of the alloy, it is necessary to strictly adjust the heat treatment conditions. I discovered that.

The heat treatment temperature was limited to 200°C to 500°C because
The heat treatment effect does not appear below 200℃, and below 500℃
This is because if the temperature exceeds 1000 yen, the material will soften in a short period of time and the desired strength will not be obtained. The most preferable heat treatment temperature is 300°C to 400°C.

また熱処理時間を2〜20時間に限定したのは、2時間
未満では材料特性が安定せず、20時間を越える熱処理

The reason why the heat treatment time is limited to 2 to 20 hours is because the material properties will not be stabilized if the heat treatment time is less than 2 hours, and the economic value will be lost if the heat treatment time exceeds 20 hours.
