Heterogeneous wire and pane provided with such a wire

摘要

A heterogeneous wire is disclosed which has a cladding comprising fibers of tungsten and fibers of copper and a core of the eutectic mixture of copper and silver. This eutectic mixture also connects the fibers of the cladding to each other. The wire has a high tensile strength, a low resistivity and a high ratio between these specific properties. As a result, the wire, which has a diameter of less than 50 mu m, is particularly suitable to be embedded in a pane.
