Abstract
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.
