There is no one that satisfies all of the required characteristics in 6). For example, among Cu alloys, as a fuse alloy for large current,
Some Cu-Fe alloys are used, but since they are precipitation hardened, they have moderate strength, but because the Fe precipitation is uneven, the electrical conductivity changes. It is difficult to obtain stable fusing characteristics. There was also the problem that it was easily corroded due to the precipitation of Fe.

本発明合金は、高強度で耐熱性も良好であり、加熱され
ても析出硬化型の銅合金と違って導電率もあまり変化し
ないため、ヒユーズ用銅合金に非常に適していることを
見出した。(Detailed Description of the Invention) The alloy of the present invention has high strength and good heat resistance, and unlike precipitation hardening copper alloys, the electrical conductivity does not change much even when heated, so it is very suitable for copper alloys for fuses. I found it suitable.
次に本発明を構成する合金成分の限定理由について説明
するｍ Ｎ ｉ−Ｚ ｎはＣｕ中に固溶させることによ
り、十分な強度を得ることができる。Next, the reasons for limiting the alloy components constituting the present invention will be explained. Sufficient strength can be obtained by incorporating mN i-Zn into Cu as a solid solution.
Ｎｉ含有量を７〜２５ｗｔ％と限定する理由は、Ｎｉ含
有量が７ｗｔ％未満では十分な強度が得られず、しかも
耐食性もあまり向上しない。さらに導電率も高いため安
定した溶断特性が得られない。The reason why the Ni content is limited to 7 to 25 wt% is that if the Ni content is less than 7 wt%, sufficient strength cannot be obtained and corrosion resistance does not improve much. Furthermore, since the conductivity is high, stable fusing characteristics cannot be obtained.
Ｎｉ含有量が２５ｗｔ％を越えると、強度は得られるが
、加工性が劣化し、価格も高くなるためである。This is because if the Ni content exceeds 25 wt%, strength can be obtained, but workability deteriorates and the price increases.
Ｚｎ含有量を５〜３２ｗｔ％と限定する理由は、やはり
強度を向上させるためであるが、５ｗｔ％未満ではその
効果がなく、３２ｗｔ％を越えると、加工性が劣化する
ためである。The reason why the Zn content is limited to 5 to 32 wt% is to improve the strength, but if it is less than 5 wt%, there is no effect, and if it exceeds 32 wt%, workability deteriorates.
副成分としてＰ、Ｓｎ、Ｓｉ、Ｍｇ、Ｔｉ、Ｃｒ、Ｚｒ

The reason for adding O is to improve strength and corrosion resistance, but if it is less than 1wt% O, it has no effect, and if it is less than 5wt%
If this value is exceeded, sufficient strength can be obtained, but workability deteriorates, and if these additive elements precipitate unevenly at grain boundaries, stable strength and conductivity with little variation cannot be obtained. It is.
