Copper-nickel-zinc alloy and use thereof

The invention relates to a copper-nickel-zinc alloy with the following composition in weight percentages: 46.0 to 51.0% Cu, 8.0 to 11.0% Ni, 0.2 to 0.6% Mn, 0.05 to 0.5% Si, up to 0.8% of each of Fe and/or Co, the sum of the Fe content and double the Co content equaling at least 0.1 wt.%, residual Zn, and unavoidable impurities, wherein nickel-, iron-, and manganese-containing and/or nickel-, cobalt-, and manganese-containing mixed silicides are embedded into a microstructure consisting of [alpha]- and [beta]-phases as spherical or ellipsoidal particles. The invention further relates to uses of a copper-nickel-zinc alloy according to the invention. 本发明涉及铜镍锌合金，其具有以下由重量百分比表示的组成：46.0％至51.0％的Cu，8.0％至11.0％的Ni，0.2％至0.6％的Mn，0.05％至0.5％的Si，各自最高达0.8％的Fe和/或Co，其中Fe含量和两倍Co含量的总和为至少0.1％，余量的Zn和不可避免的杂质，其中含有镍、铁和锰的和/或含镍、钴和锰的混合硅化物作为球形或椭圆形颗粒嵌入由α相和β相组成的微观结构中。本发明进步涉及根据本发明的铜镍锌合金的应用。
