Material for a metal strip

An electrically conductive metal tape for manufacturing electrical contact components and a plug connector made of it. The metal tape has a base material made of copper or a copper alloy having a metallic coating, applied by molten technology, made of a tin-silver alloy containing a silver proportion between 1% and 3.8% by weight. The silver content in the coating preferably lies between 1.2% by weight and 2.5% by weight. Especially positive properties with respect to the adhesiveness between base material and metal coating are achieved by the silver proportion in the coating. At the same time, the temperature stability and sliding properties are improved. Furthermore, a stable contact resistance is ensured.

Electrically conductive metal tape and plug connector

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.
