电接触元件的材料
摘要：
本发明涉及用于用来制造电接触元件的金属带的材料，以及这种材料用于电接触元件，特别是插塞接点的用途。所述材料由具有下列合金组分的可硬化的铜合金构成，以重量％计：锌(Zn)19.0％至40.0％锡(Sn)0.1％至1.5％镍(Ni)0.8％至3.0％硅(Si)0.1％至0.9％，以及任选地至少一种来自以下组的元素：磷(P)、硼(B)、银(Ag)、锰(Mn)、铬(Cr)、铝(Al)、镁(Mg)、铁(Fe)、锆(Zr)或砷(As)，其中，来自该组的单个元素的份额为最高0.8％，来自该组的所有元素的份额为最高4.55％，其余的是铜(Cu)和熔炼产生的杂质。镍(Ni)的份额可至少部分地被钴(Co)代替，其中镍(Ni)和/或钴(Co)与硅(Si)的比例达到3.5:1至7.5:1。
摘要（英）：

The invention relates to a material for a metal strip for manufacturing electric contact components and to the use of such a material for electric contact components, in particular plug contacts. Said material consists of a copper alloy which can be hardened and which comprises the following alloy components in weight percentages: zinc (Zn) 19.0% to 40.0%; tin (Sn) 0.1% to 1.5%; nickel (Ni) 0.8% to 3.0%; silicon (Si) 0.1% to 0.9%; and optionally at least one element of the following group: phosphorus (P), boron (B), silver (Ag), manganese (Mn), chromium (Cr), aluminum (Al), magnesium (Mg), iron (Fe), zirconium (Zr), or arsenic (As), wherein the percentage of each individual element of the group is maximally 0.8% and the percentage of all the elements of the group is maximally 4.55%; residual copper (Cu); and impurities resulting from the melting process. The percentage of nickel (Ni) can be at least partly replaced by cobalt (Co), and the ratio of nickel (Ni) and/or cobalt (Co) to silicon (Si) ranges from 3.5 : 1 to 7.5 : 1.
