本発明は機械的特性並びに電気的特性のバランスのすぐ
れた配電線、巻線、通信線などに特に好適な導電用アル
ミニウム合金に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conductive aluminum alloy that has well-balanced mechanical properties and electrical properties and is particularly suitable for use in power distribution lines, winding wires, communication lines, and the like.
従来、機械的強度の高いアルミニウム合金としては熱処
理型のいわゆるイ号アルミニウム合金が知られているが
、この種の合金は製造過程に多くの熱処理を必要とする
ので作業性が悪く、コスト高となる欠点を有していた。Conventionally, a heat-treated so-called No. It had some drawbacks.
また熱処理型の他に加工硬化型の合金として５００５合
金が知られているが、この種の合金は機械的強度と導電
率のバランスが良くとれておらず導体材料として充分満
足のいくものではなかった。In addition to the heat treatment type, 5005 alloy is known as a work hardening type alloy, but this type of alloy does not have a good balance between mechanical strength and electrical conductivity and is not fully satisfactory as a conductor material. Ta.
さらに電気用アルミニウム（以下Ｅ Ｃ −Ａ ＃とい
う）は電気的特性は優れているが、機械的強度が劣ると
いう欠点があった。Further, although electrical aluminum (hereinafter referred to as E C -A #) has excellent electrical properties, it has a drawback of poor mechanical strength.
しかして本発明は上記の点に鑑み、電気的特性並びに機
械的性質のバランスのよい導電用アルミニウムを提供せ
んとするものであり、その要点はＦ ｅ Ｏ．４ ０
〜０．８ ０％、Ｃ ｏ Ｏ．１ ０〜０．３ ０％、
Ｃ ｕ Ｏ．０ ３〜０．２ ０％、残部Ａｌおよび不
可避な不純物からなる合金に、さらにＡ ｇ ０．０
０１〜０．１０％を添加した導電用アルミニウム合金で
ある。In view of the above points, the present invention aims to provide conductive aluminum with well-balanced electrical properties and mechanical properties, and the main point is that F e O. 4 0
~0.80%, C o O. 10-0.30%,
C u O. 0 3 to 0.2 0%, the balance Al and unavoidable impurities, and further A g 0.0
This is an aluminum alloy for conductivity to which 0.01 to 0.10% is added.
Ｆｅ，ＣｏはＡ７と種々の金属間化合物を形成し、これ
ら金属間化合物は熱間加工あるいは伸線加工で細かく破
砕され、アルミマトリックスに分散してＡｌを分散強化
する。Fe and Co form various intermetallic compounds with A7, and these intermetallic compounds are finely crushed by hot working or wire drawing and dispersed in an aluminum matrix to disperse and strengthen Al.
しかもＦｅ，ＣｏはＡ７に極めて微量（約０．０５％）
しか固溶しないので導電率はこれらの添加によってはあ
まり低下することはない。Moreover, Fe and Co are present in extremely small amounts (approximately 0.05%) in A7.
Since these elements are only dissolved in solid solution, the conductivity is not significantly reduced by the addition of these elements.
しかして金属間化合物をアルミマトリックスに微細に分
散させるためには Ｆ ｅ，Ｃｏを固溶限度以上添加し
なければならない。However, in order to finely disperse the intermetallic compound in the aluminum matrix, it is necessary to add Fe and Co above the solid solution limit.
実際に所望の機械的強度を得るためにはＦｅ，Ｃｏをそ
れぞれ０．４０％、０．１０％以上添加する必要がある
。In order to actually obtain the desired mechanical strength, it is necessary to add 0.40% or more of Co and 0.40% or more of Co, respectively.
またＦｅ，Ｃｏの添加量がそれぞれ０．８０％、０．３
０％を越えると逆に加工性が低下する。In addition, the amounts of Fe and Co added are 0.80% and 0.3%, respectively.
If it exceeds 0%, workability will decrease.
ＣｕはＡｌに固溶し、導電性をあまり低下させることな
く固啓強化させ、機械的性質を向上させる。Cu forms a solid solution in Al, strengthens the conductivity without significantly reducing conductivity, and improves mechanical properties.
そのためにはＣｕを０．０３％以上添加する必要がある
。For this purpose, it is necessary to add 0.03% or more of Cu.
しかしＣｕの添加量が０．２０％を越えると耐食性、導
電性が劣化する。However, when the amount of Cu added exceeds 0.20%, corrosion resistance and conductivity deteriorate.
さらに前記合金にＡｇを添加すると、ＡｇはＡｌと共晶
反応を起こし、アルミマトリックスに微細に分散してＡ
ＪＩ？を分散強化して機械的性質を向上させると同時に
導電性を回復させる。Furthermore, when Ag is added to the alloy, Ag causes a eutectic reaction with Al, and is finely dispersed in the aluminum matrix.
JI? dispersion strengthens to improve mechanical properties and at the same time restore conductivity.
この理由についてはＡｇがアルミマトリックス中に固溶
している微量不純物と金属間化合物を形成して析出する
ためと思われる。The reason for this is thought to be that Ag forms an intermetallic compound with trace impurities dissolved in the aluminum matrix and precipitates.
そのためにはＡｇの添加量を０．００１％以上とする必
要がある。For this purpose, the amount of Ag added must be 0.001% or more.
しかしＡｇを０．１０％より多く添加すると導電性が劣
化する。However, when more than 0.10% of Ag is added, the conductivity deteriorates.
以下に本発明を実施例につき説明する。The invention will be explained below with reference to examples.
これにより本発明の顕著な効果を明らかにする。This makes clear the remarkable effects of the present invention.
実施例
ＥＣ−Ａ７地金を溶解し、Ｆｅ ，Ｃｏ ，Ｃｕを種々
の割合いで添加し、さらにＡｇを種々の割合いで添加し
て溶解させた後、２０φＸ３００Ｌの金型に鋳造しビレ
ットとした。Example EC-A7 Ingot was melted, Fe, Co, and Cu were added in various proportions, and Ag was added in various proportions and melted, and then cast into a 20φ×300L mold to form a billet.
このビレットをスエージ加工して、９．５φの荒引線と
した後、冷間伸線して３．６φとし、引張強さ（σＢ）
および導電率（λ）を測定した。This billet was swaged to make a rough drawn wire of 9.5φ, then cold drawn to 3.6φ, and the tensile strength (σB)
and conductivity (λ) were measured.
その結果を第１表に示す。なお比較のため、ＥＣ−Ａ７
，イ号アルミおよび５００５の測定値もあわせて第１表
に示す。The results are shown in Table 1. For comparison, EC-A7
, No. I aluminum and 5005 are also shown in Table 1.
また軟質状態での特性を第２表に示す。Table 2 shows the properties in a soft state.
第１表および第２表より、ＥＣ−．１は導電率は高いが
、引張強さが小さく、イ号アルミおよび５００５は引張
強さは大きいが導電率が低いことがわかる。From Tables 1 and 2, EC-. It can be seen that No. 1 has high conductivity but low tensile strength, and No. I aluminum and 5005 have high tensile strength but low conductivity.
それに対し、本発明に従ってＦｅ ，Ｃｏ ，Ｃｕ，Ａ
ｇを添加したものは導電率を劣化させることなしに引張
強さを向上させ得た。In contrast, according to the present invention, Fe, Co, Cu, A
The addition of g could improve the tensile strength without deteriorating the electrical conductivity.
以上のように本発明に係る導電用アルミニウム合金は殊
更熱処理を施さなくても引張強さと導電性とのバランス
がよく、優れた機械的性質および電気的特性がともに要
求される配電線、巻線、通信線などの導電材料に好適に
使用し得るものである。As described above, the conductive aluminum alloy according to the present invention has a good balance between tensile strength and conductivity without special heat treatment, and can be used for distribution wires and windings that require both excellent mechanical properties and electrical properties. , it can be suitably used for conductive materials such as communication lines.
