Abstract
A wire electrode for cutting by electrical discharge machining may include a core and a covering. The core may include a metal or a metal alloy. The covering may surround the core and may include one or more covering layers, of which at least one contains a mixture of phases including at least one of β or β' brass and including γ brass. In the at least one covering layer that contains the mixture, the phases are present next to one another in a fine-grained microstructure having a mean grain size of 5 μm or less in section perpendicular to the longitudinal axis of the wire electrode.
