Abstract
An electrode wire for electrical discharge machining included: a core made of first metal; and an alloy layer which is formed at an outer circumference of the core due to inter-dispersion of the core and second metal with which an outer surface of the core is plated. The alloy layer includes a portion formed by α phase+β′ phase and β′ phase grains. The alloy layer has cracks formed at a surface thereof. According to such a configuration described above, there can be provided an electrode wire for electrical discharge machining which has an even surface, improves a machining speed and the surface roughness of a workpiece, and minimizes generation of fine debris of the electrode wire.
