Abstract
Abstract A wire electrode consists of Cu (alloy) core of alpha phase with a coating of Zn (alloy). The coating is produced so that no diffusion takes place between the core and coating. The electrode is then annealed at 500-800 degrees C using a heating up speed of at least 10 degrees /sec. and held at this temp. for 10-300 sec. depending on the required coating thickness and phase structure. It is finally cooled at a rate of above 10 degrees /sec.
