A wire electrode for spark erosion is proposed, having a total diameter between 0.05 and 0.4 mm, an inner steel core made of steel and an outer coating surrounding the steel core, which electrode is cost-effective and simultaneously satisfies the mechanical and electrical demands placed thereon, it is further proposed that the coating has an iron-zinc alloy layer and the thickness of the iron-zinc alloy layer at its thinnest point is greater than 5% of the total diameter and at its thickest point is less than 25% of the total diameter. |
