Abstract
The invention concerns an electrode wire comprising an unalloyed copper core coated with a diffused zinc alloy coating layer, whereof the thickness is more than 10% of the wire diameter. The coating layer is optionally plated with a thin zinc, copper, nickel, silver or gold surface contact film. Such a wire achieves higher electrical discharge machining speed.
