Abstract (en)
[origin: WO2014198254A1] The invention relates to a wire electrode (1) for spark erosion having a total diameter (D) between 0.05 and 0.4 mm, an inner steel core (2) composed of steel, and an outer jacket (3) surrounding the steel core (2). The problem addressed by the invention is that of providing a wire electrode (1) that is economical and at the same time meets the mechanical and electrical requirements placed on the wire electrode. This problem is solved in that the jacket (3) has an iron-zinc alloy layer (4) and the thickness (d) of the iron-zinc alloy layer is greater than 5% of the total diameter (D) at the thinnest point of the iron-zinc alloy layer and is less than 25% of the total diameter (D) at the thickest point of the iron-zinc alloy layer.
