Description
導電率が98%IACS以上の軟質銅材を得る場合、不可避的不純物を含む純銅(ベース素材)が、3〜12mass ppmの硫黄と、2〜30mass ppmの酸素と、Tiを4〜55mass ppm含む希薄銅合金材料でワイヤロッド(荒引き線)を製造するものである。
分散粒子のサイズは小さく沢山分布することが望ましい。その理由は、硫黄の析出サイトとして働くためサイズが小さく数が多いことが要求される。
SCR連続鋳造圧延によりワイヤロッドを造る。一例として、加工度99.3%でφ8mmのワイヤロッドを造る方法を用いる。
高純度Cu(6N)の軟化温度は127〜130℃であったので、得られたデータから限界値を130℃とする。このわずかな違いは、高純度Cu(6N)にない不可避的不純物にある。
銅はシャフト炉で溶解の後、還元状態の樋になるように制御した、すなわち還元ガス(CO)雰囲気下で、希薄合金の構成元素の硫黄濃度、Ti濃度、酸素濃度を制御して鋳造し、圧延するワイヤロッドを安定して製造する方法がよい。銅酸化物の混入や粒子サイズが大きいので品質を低下させる。
また、本発明の希薄銅合金線の表面にめっき層を形成してもよい。めっき層としては、例えば、錫、ニッケル、銀を主成分とするものを適用可能であり、いわゆるPbフリーめっきを用いてもよい。
また、本発明の希薄銅合金線を複数本撚り合わせた希薄銅合金撚線として使用することも可能である。
また、本発明の希薄銅合金線又は希薄銅合金撚線の周りに、絶縁層を設けたケーブルとして使用することもできる。
また、本発明の希薄銅合金線を複数本撚り合わせて中心導体とし、中心導体の外周に絶縁体被覆を形成し、絶縁体被覆の外周に銅又は銅合金からなる外部導体を配置し、その外周にジャケット層を設けた同軸ケーブルとして使用することもできる。
また、この同軸ケーブルの複数本をシールド層内に配置し、前記シールド層の外周にシースを設けた複合ケーブルとして使用することもできる。
Claims (5)
- 2〜12mass ppmの硫黄と、2〜30mass ppmの酸素と、4〜55mass ppmのTiを含み残部が銅からなる銅合金材料を素材として連続鋳造圧延法で作製されたワイヤロッドを冷間伸線加工したものであって、前記ワイヤロッドを加工度90%で冷間伸線して得られた希薄銅合金線であって、当該希薄銅合金線の導電率が98%IACS以上であり、半軟化温度が130〜148℃であることを特徴とする希薄銅合金線。
- 前記Tiの濃度が37mass ppm以下で、前記希薄銅合金線の導電率が100%IACS以上である請求項1に記載の希薄銅合金線。
- 前記Tiの濃度が25mass ppm以下であり、前記希薄銅合金線の導電率が102%IACS以上である請求項1に記載の希薄銅合金線。
- 請求項1〜3のいずれかに記載の希薄銅合金線の表面にめっき層を形成したことを特徴とするめっき線。
- 請求項1〜4いずれかに記載の希薄銅合金線又はめっき線を複数本撚り合わせたことを特徴とする撚線。
