    Abstract: A wire comprising a wire core with a surface, the wire core having a coating layer superimposed on its surface, wherein the wire core itself consists of: (a) silver in an amount of from 0.1 to 0.3 wt.-%, (b) copper in an amount in the range of from 99.64 to 99.9 wt.-%, (c) phosphorus in an amount in the range of from 0 to 100 wt.-ppm, and (d) further components (components other than silver, copper and phosphorus) in an amount in the range of from 0 to 500 wt.-ppm, wherein the individual amount of any further component is less than 30 wt.-ppm, wherein all amounts in wt.-% and wt.-ppm are based on the total weight of the core, and wherein the coating layer is a double-layer comprised of an inner layer of palladium and an adjacent outer layer of gold, wherein the weight of the inner palladium layer is in the range of 1.5 to 2.5 wt.-%, relative to the weight of the wire core, and wherein the weight of the outer gold layer is in the range of 0.09 to 0.18 wt.-%, relative to the weight of the wire core.
