Abstract

See full text

In order to produce a wire electrode having a core consisting of a copper/zinc alloy and to produce a specific sheath layer, the sheath layer is coated onto the core at a temperature at which no diffusion occurs. The wire electrode is subsequently heated at a heating speed higher than 10° C. per second, briefly annealed at temperatures above 500° C. and subsequently cooled again very rapidly at cooling speeds higher than 10° C. per second.
