Title:

ELECTRODE WIRE FOR ELECTRICAL DISCHARGE MACHINING AND MANUFACTURING METHOD FOR SAME

Document Type and Number:

WIPO Patent Application WO/2016/072033

Kind Code:

A1

Abstract:

An electrode wire for electrical discharge machining having zinc coating on the outer circumference of a core material, wherein the electrode wire for electrical discharge machining has excellent automatic wire connectivity during electrical discharge machining, and a manufacturing method for same are provided. The present invention is an electrode wire for electrical discharge machining 10, wherein the outer circumference of a core material 1 made of copper or a copper alloy is coated with a coating layer 2 containing zinc, the coating layer 2 comprises an inner layer 2A that contains a γ-phase copper-zinc based alloy covering the outer circumference on the core material 1 and an outer layer 2B that contains an ε-phase copper-zinc based alloy covering the outer circumference of the inner layer 2A, and the (0001) x-ray diffraction intensity of the ε-phase is at least twice the (332) x-ray diffraction intensity of the γ-phase.
