Abstract
The electrode wire according to the invention comprises a brass core (1) covered with a γ phase brass coating (2) having a structure fragmented into blocks (2a) between which the core (1) is exposed. The blocks (2a) have a thickness (E2) with a narrow distribution and produce a coverage of the core (1) according to a coverage rate greater than 50%. This produces a regular fragmentation of the coating, which improves the finish state of the machined parts.
