Abstract:
(EN) The present invention relates to a level wound coil in which a seamless pipe is aligned and wound in multiple layers in a cylindrical shape. The material of the seamless pipe wound around the level wound coil contains between 0.58 and 0.72 mass% of Sn, between 0.005 and 0.035 mass% of Zr, between 0.01 and 0.10 mass% of Fe, and between 0.004 and 0.040 mass% of P, and is a copper alloy made of a balance of Cu and unavoidable impurities. The ratio (t/D) of the thickness (mm) to the outer diameter (mm) of the seamless pipe wound around the level wound coil is 0.040 or less, the tensile strength of the seamless pipe wound around the level wound coil (σB) is at least 280 MPa, the 0.2% proof stress (σ0.2) is 180 MPa or less, and the elongation (δ) is at least 38%. The present invention can provide a seamless pipe that has high strength, can normally perform a hairpin bend, and is formed of copper alloy can be provided.
(FR) La présente invention concerne une bobine trancannée dans laquelle un tuyau sans soudure est aligné et enroulé en plusieurs couches sous une forme cylindrique. Le matériau du tuyau sans soudure enroulé autour de la bobine trancannée contient entre 0,58 et 0,72 % en poids de Sn, entre 0,005 et 0,035 % en poids de Zr, entre 0,01 et 0,10 % en poids de Fe et entre 0,004 et 0,040 % en poids de P, et est un alliage de cuivre composé, pour le reste, de Cu et d'inévitables impuretés. Le rapport (t/D) de l'épaisseur (mm) sur le diamètre extérieur (mm) du tuyau sans soudure enroulé autour de la bobine trancannée est inférieur ou égal à 0,040, la résistance à la traction (σB) du tuyau sans soudure enroulé autour de la bobine trancannée est d'au moins 280 MPa, la limite conventionnelle d'élasticité à 0,2% (σ0,2) est inférieure ou égale à 180 MPa, et l'allongement (δ) est d'au moins 38 %. La présente invention permet d'obtenir un tuyau sans soudure qui présente une grande résistance, peut normalement être plié en épingle à cheveux et est composé d'un alliage de cuivre.
(JA)  継目無管が円筒状に整列多層巻きされているレベルワウンドコイルであり、該レベルワウンドコイルに巻かれている該継目無管の材質が、0.58~0.72質量%のSn、0.005~0.035質量%のZr、0.01~0.10質量%のFe及び0.004~0.040質量%のPを含有し、残部Cu及び不可避不純物からなる銅合金であり、該レベルワウンドコイルに巻かれている該継目無管の外径(mm)に対する肉厚(mm)の比(t/D)が0.040以下であり、該レベルワウンドコイルに巻かれている継目無管の引張強さ(σ)が280MPa以上であり、0.2%耐力(σ0.2)が180MPa以下であり、伸び(δ)が38%以上であること、を特徴とするレベルワウンドコイル。 本発明によれば、強度が高く且つヘアピン曲げを正常に行うことができる銅合金製の継目無管を提供することができる。
