A WIRE ELECTRODE FOR USE IN SPARK-EROSIVE CUTTING ABSTRACT OF THE DISCLOSURE A wire electrode for use in spark-erosive cutting. The wire electrode includes a core area and an outer coating. The wire electrode is reduced in cross section in order to achieve a high surface quality characteristic and a high strength characteristic, is subsequently diffusion annealed in an oxidizing atmosphere, is thereafter again reduced in cross section, is exposed to a recrystallizing annealing and is deformed to a final dimension. The inventive wire electrode has, on the one hand, a very even, fine-granular structure and is, on the other hand, provided with a very even and dense surface, which assures an excellent spark transfer.
