Electrically conductive metal tape and plug connector made of it

Abstract

An electrically conductive metal tape for manufacturing electrical contact components, in particular plug connectors, having a base material made of a copper alloy having nickel proportions between 1.0 and 4.0% by weight, silicon proportions of 0.08 to 1.0% by weight, tin proportions between 0.02 and 1.0% by weight, zinc proportions of 0.01 to 2.0% by weight, zirconium proportions of 0.005 to 0.2% by weight and silver proportions between 0.02 to 0.5% by weight, the coating consisting of a tin-silver alloy having a silver proportion between 1.0 and 3.8% by weight. Particularly positive properties are displayed by a metal tape whose base material is made of a copper alloy having proportions of nickel between 1.4 and 1.7% by weight, silicon from 0.2 to 0.35% by weight, tin between 0.02 and 0.3% by weight, as well as zinc from 0.01 to 0.3% by weight.
