Abstract: Disclosed herein is a wire electrode for wire cutting electro-discharge machining which can improve the processing speed as well as productivity of the wire electrode. A core (2) is made of a copper alloy containing Ag. A coating layer (1) formed on the outer periphery of the core (2) is made of a copper alloy containing Zn and Al.

Abstract: Disclosed herein is a wire conductor for a harness, comprising a central portion which is formed of aramid fiber and a conductor portion formed by circularly compressing a stranded wire which is prepared by arranging copper strands around the central portion and braiding the same. The conductor portion has a conductor sectional area of 0.03 to 0.3 mm.sup.2.

Abstract: Strands of a copper alloy containing 0.2 to 10 percent by weight of Sn are braided to form a stranded wire for a wire conductor for a harness having a conductor sectional area of 0.03 to 0.3 mm.sup.2. After the braiding, preferably stranded wire is heat treated so that its tensile strength is maintained at a prescribed level. The wire conductor for a harness has a breaking strength which is equivalent to that of a conventional harness wire, and is hardly broken by an impact. The wire conductor maintains its straightness, and strand ends do not fray upon cutting.
