Beschreibung
Zusammenfassung:	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 is a silver-based wire core, wherein the coating layer is a double-layer comprised of a 1 to 100 nm thick inner layer of nickel or palladium and an adjacent 1 to 250 nm thick outer layer of gold, characterized in that the wire exhibits a total carbon content of ≤ 40 wt.-ppm. L'invention concerne un fil comprenant une âme de fil dotée d'une surface, l'âme de fil ayant une couche de revêtement superposée sur sa surface, l'âme de fil elle-même étant une âme de fil à base d'argent, la couche de revêtement étant une double couche composée d'une couche interne de nickel ou de palladium épaisse de 1 à 100 nm et d'une couche externe d'or adjacente épaisse de 1 à 250 nm, caractérisé par le fait que le fil présente une teneur totale en carbone ≤ 40 ppm en poids.
