Zusammenfassung:	To provide a copper alloy particularly for use in electrical connection elements.SOLUTION: A copper alloy comprises, in wt.%, Sn: 3.0-6.5%; Ni: 0.30-0.70%; P: 0.15-0.40%; S: 0.10-0.40%; Zn: optionally up to 0.20%; Fe: optionally up to 0.50%; Mn: optionally up to 0.50%; Pb: optionally up to 0.25%, with the balance being copper and unavoidable impurities. The ratio of Ni content to P content is at least 1.1 and at most 2.8. The copper alloy also comprises nickel phosphides.SELECTED DRAWING: None 【課題】特に電気接続部材に使用するための、銅合金を提供する。【解決手段】本発明は、重量％で以下の組成：Ｓｎ：３．０～６．５％、Ｎｉ：０．３０～０．７０％、Ｐ：０．１５～０．４０％、Ｓ：０．１０～０．４０％、Ｚｎ：任意に０．２０％まで、Ｆｅ：任意に０．５０％まで、Ｍｎ：任意に０．５０％まで、Ｐｂ：任意に０．２５％まで、残部銅ならびに不可避な不純物を有する銅合金であって、Ｐの含量に対するＮｉの含量の比が少なくとも１．１かつ多くとも２．８であり、およびリン化ニッケルを含有する、銅合金に関する。【選択図】なし
