Abstract

To inexpensively provide a copper alloy wire material that has high extensibility and exceptional workability, specifically, coil shaping properties, and that moreover imparts exceptional characteristics (coil life) to coils obtained using the copper alloy wire material, the material being intended for use, e.g. as magnet wire or the like. Provided are a copper alloy wire material containing 0.1-4 mass% of Ag, and / or 0.05-0.30 mass%, expressed as individual content, of at least one element selected from the group consisting of Sn, Mg, Zn, In, Ni, Co, Zr, and Cr, the remainder being Cu and unavoidable impurities, wherein when a cross section perpendicular to the lengthwise direction of the wire material is observed from the normal line direction by an EBSD technique, the area ratio of crystal grains having (101) orientation is 10% or more of the total measured surface area; and a method for manufacturing the material.

Description

technical field [0001] The invention relates to a copper alloy wire and a manufacturing method thereof, in particular to an ultra-fine copper alloy wire for a magnetic wire and a manufacturing method thereof. Background technique [0002] With the development of electronic equipment, the miniaturization of electronic components is being promoted, and the demand for ultra-fine copper alloy wires with a wire diameter of 0.1mm or less is increasing. For example, microspeaker coils used in mobile phones, smartphones, etc. are manufactured by winding extremely thin wires (magnet wires) with a wire diameter of 0.1 mm or less into a coil shape. [0003] In this winding process, toughness (elongation) to the extent that a bend can be formed is required, and therefore pure copper excellent in toughness has been used conventionally. However, although pure copper has excellent electrical conductivity, its strength is low. In addition, since the fatigue resistance due to coil vibratio...
