る（特公昭４９−１０８９４号）。Copper alloys that exhibit excellent mechanical properties such as electrical conductivity and tensile strength over a wide temperature range are known, such as copper alloys that contain magnesium and phosphorus in specific amounts (Tokuko Showa). No. 49-10894).

十分な強度を維持できない。In recent years, with the development of electronic devices, they have become increasingly lighter, thinner, and shorter, and as a result, the conductors for wiring in electronic devices are also becoming smaller in diameter. 1. For example, in the copper alloy containing Mg and P according to the above-mentioned Japanese Patent Publication No. 49-10894, when a conductor with a small diameter of about 0.3 msφ to O, O1s + sφ is made, during the manufacturing process of electronic equipment. Cannot maintain sufficient strength against applied heat.

られない。That is, since the heat resistance is not sufficient, the parts that are sometimes heated during brazing become mechanical weak points and are prone to wire breakage. Furthermore, the above-mentioned zirconium copper has the disadvantage that it is prone to breakage at terminal crimping connection points of the conductor, since it lacks repeated bending strength. Incidentally, in this case, even if an attempt is made to increase the strength by increasing the zirconium content, the content will vary, making it impossible to obtain an alloy of stable quality.

は加熱下での繰返し曲げや引張を受けることになる。Furthermore, since industrial robots repeatedly operate up to the taught position, the robot cable conductors used in these robots are constantly subjected to repeated bending and tension, making them susceptible to wire breakage. In addition,
Cable conductors for industrial robots used in high-temperature environments are subjected to repeated bending and tension under heating.
したがって、このような条件下では導体の繰返し曲げ強

In addition to good electrical conductivity, there is a need to provide conductors that have improved cyclic bending strength and tensile strength. .

に銅から成る銅合金にある。The characteristics of the light plate public keyaki sole of the present invention are that magnesium is 0.02 to 0.5% by weight, phosphorus is 35 to 100% by weight relative to magnesium, and lead is 0.9% by weight. It is a copper alloy containing 1 to 0.5% by weight of O, with the balance essentially consisting of copper.

量％添加する。The copper alloy according to the present invention for the purpose of improving the mechanical strength of the copper alloy is produced by adding 0.02 to 0.0% Mg to electrolytic copper as a base material, mainly to increase its mechanical strength.
5% by weight, 35 to 100% by weight of P to Mg to further improve its strength, and 0.01 to 0.5% by weight of Pb to improve tensile strength and fiber return bending strength. Added.
上記各元素を上記の各特定範囲に添加する根拠は下記理
由に基づく。The basis for adding each of the above elements to each of the above specific ranges is based on the following reasons.
Ｍｇについては、その添加量が０．５重量％を超えると
得られる銅合金の導電性の低下が大きくなり、加うるに
Ｍｇの銅合金における含有量の制御が難しいので、銅合
金の品質が不安定となる。一方、Ｍｇが０．０２２重丸
未満では繰返し曲げ強度及び引張強度の改善効果が少く
なる。また、Ｐについては、その添加量が特定範囲の下
限未満ではＰの添加効果が発揮されず、一方上限を超え
ると銅合金の導電性を却って損うようになる。Regarding Mg, if the amount added exceeds 0.5% by weight, the conductivity of the resulting copper alloy will decrease significantly, and in addition, it is difficult to control the Mg content in the copper alloy, so the quality of the copper alloy will deteriorate. Becomes unstable. On the other hand, if the Mg content is less than 0.022 circles, the effect of improving repeated bending strength and tensile strength will be reduced. Regarding P, if the amount added is less than the lower limit of the specific range, the effect of adding P will not be exhibited, while if it exceeds the upper limit, the conductivity of the copper alloy will be impaired.
次に、ｐｂの添加量については、０．０１重量％未満で
は、繰返し曲げ強度及び引張強度の向上効果が十分でな
く、一方０．５重量％を超えると銅合金の高導電性を維
持できなくなる。Next, regarding the amount of PB added, if it is less than 0.01% by weight, the effect of improving the cyclic bending strength and tensile strength will not be sufficient, while if it exceeds 0.5% by weight, the high conductivity of the copper alloy cannot be maintained. It disappears.
