摘要： PROBLEM TO BE SOLVED: To provide a copper wire formed from pure copper and having high strength and high toughness; a coated electrical wire which uses the copper wire as a conductor; and a method for manufacturing the copper wire. SOLUTION: This manufacturing method includes: subjecting a base material containing 99.9 mass% or more Cu to cold working; then subjecting the base material to intermediate heat treatment; subjecting the obtained intermediate heat-treated material to final cold working to produce a drawn wire having a final wire diameter of 0.1-2.0 mm; and subjecting the drawn wire to final heat treatment. The intermediate heat treatment is conducted when the working degree of the final cold working which is conducted right after the intermediate heat treatment satisfies 85-95%. The copper wire having a fine structure with an average crystal grain size of 20 μm or less can be obtained by conducting the intermediate heat treatment so as to control the working degree of the final cold working within a particular range and also conducting the final heat treatment after the final cold working. The copper wire has high strength, high toughness, a tensile strength of 240 MPa or more and an elongation of 20% or more. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a copper stock for a wire rod which contributes to improvement of productivity of the wire rod by reducing disconnection and surface defects of the wire rod when manufacturing a copper-based wire rod made of copper or copper alloy, the copper stock for the wire rod, the copper based wire rod, and a method for manufacturing the copper based wire rod.SOLUTION: Scalping is carried out by using a scalping die 100 to a bar-shaped stock 10 made of the copper or the copper alloy, and subjected to at least casting thereto. The scalping satisfies at least any one of the conditions of (A)-(C): (A) the removal amount by scalping is 1-10% by the sectional area ratio; (B) the drawing degree before the scalping is drawing of 15-75%; and (C) the rake angle θ of a cutting blade 120 is 2-5°. The copper-based wire rod is manufactured by applying drawing to the obtained scalped material until the desired final wire diameter is obtained. By applying the scalping to the bar-shaped stock 10 under the specified condition, the copper stock for the wire rod having excellent surface property is obtained. By applying drawing to the stock, the copper-based wire rod which is hardly disconnected during the drawing and excellent in surface property can be manufactured with high productivity.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive rectangular conductor superior in breaking strength.
SOLUTION: This rectangular conductor is formed by means that tough pitch soft copper wires formed of tough pitch copper of which spiral elongation is within the range of 50-350 mm are compressed. It is preferable that the compressing is carried out within the range of draft of 60-90%. Then, after the compressing, the compressing may be carried out further at the draft of 40% or less. Moreover, after the first step compressing, heat treating may be carried out.
