Wire electrode for electroerosion cutting

Abstract

Abstract The invention relates to a wire electrode for electroerosion cutting which comprises a core region and a cladding layer. To achieve a high surface quality and a high strength, the wire electrode is reduced in cross section, then diffusion-annealed in an oxidising atmosphere, again reduced in cross section, subjected to a recrystallising anneal and worked to the final dimension. The wire electrode according to the invention has, on the one hand, a very uniform, fine-grained structure and, on the other hand, is provided with a very uniform and compact surface which ensures an excellent spark discharge. <IMAGE>
