Title:
放電加工用電極線の製造方法
Document Type and Number:
Japanese Patent JP6418507
Kind Code:
B2
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 ³-phase copper-zinc based alloy covering the outer circumference on the core material 1 and an outer layer 2B that contains an µ-phase copper-zinc based alloy covering the outer circumference of the inner layer 2A, and the (0001) x-ray diffraction intensity of the µ-phase is at least twice the (332) x-ray diffraction intensity of the ³-phase.
