    • A nickel-free white copper alloy material, wherein a white coating layer containing no Ni is formed on a base material composed of an alloy represented by the general formula: Cu a Zn b Mn c M d X e ,wherein M is at least one element selected from the group consisting of Al and Sn; X is at least one element selected from the group consisting of Si, Ti and Cr; b, c, d and e are 0≤b≤22, 7≤c≤20, 0≤d≤5 and 0≤e≤0.3 in terms of % by weight; and a is the balance, the alloy incidentally including unavoidable elements. The white copper alloy material has excellent strength and hardness equal to those nickel silver, as well as excellent workability, corrosion resistance and whiteness in addition to ductility, and has no fear of allergic reactions because of containing no Ni. In the white copper alloy material, fine adjustment of its white hue is possible according to the demand of customers, and satisfactory mechanical properties can be obtained with the desired hue.
    • 在由通式CuaZnbMncMdXe表示的合金构成的基材上形成不含Ni的白色被覆层的无镍白铜合金材料,其中,M为选自Al和 锡; X是选自Si,Ti和Cr中的至少一种元素; b,c,d和e分别为0≤b≤22,7≤c≤20,0≤d≤5,0≤e≤0.3; 而a是平衡,合金偶然地包括不可避免的元素。 白铜合金材料具有与镍银相当的优异的强度和硬度,以及除了延展性之外具有优异的加工性,耐腐蚀性和白度,并且不含不含Ni的过敏反应的恐惧。 在白铜合金材料中,根据客户的要求,可以对其白色调进行精细调整,并可获得满意的机械性能。

    • An object of the present invention is to provide, through plating, a slide fastener which has high decorativeness, and which does not have problems in terms of functionality or product quality such as corrosion resistance. Another object is to provide a method of manufacturing an attachment having constituent members.
      In a slide fastener in which a large number of elements are mounted on an edge of a pair of mutually facing slide fastener tapes, each of the elements has a facing surface where elements face one another in a longitudinal direction of the slide fastener tapes, and a surface other than the facing surface, a coating is formed through electroless plating on the facing surface, and a coating is formed through electrolytic plating on the surface other than the facing surface. The coating on the surface other than the facing surface is made to be a single-layer or multi-layer coating selected from Sn, Cu-Sn alloy, Cu-Sn-Zn alloy, Rh, Pd, and Cu plating, and the coating on the facing surface is Sn plating.
    • 本发明的目的是通过电镀提供具有高装饰性的拉链,并且在诸如耐腐蚀性的功能性或产品质量方面没有问题。 另一个目的是提供一种制造具有构件的附件的方法。 在其中大量元件安装在一对相互面对的拉链带的边缘上的拉链中,每个元件具有面向表面,其中元件在拉链带的纵向方向上彼此面对,并且 除了相对表面之外的表面,通过在相对表面上的无电镀形成涂层,并且在面对面以外的表面上通过电解电镀形成涂层。 除了表面以外的表面上的涂层是选自Sn,Cu-Sn合金,Cu-Sn-Zn合金,Rh,Pd和Cu电镀的单层或多层涂层,涂层 在正面是Sn镀层。
