<p>The invention relates to a wire electrode (1) for spark-erosion cutting. The wire electrode (1) comprises a core (2) made of more than 50 % by weight pure crystalline aluminum and/or one or more crystalline aluminum alloys, and comprises a coating layer (3) encompassing the core (2) and comprising copper, zinc, and/or a copper-zinc alloy. The proportion of the surface area of the core (2) relative to the total cross-sectional area of the wire electrode (1) is in the range from 60% to 95% along the entire length of the wire electrode (1).</p> |
