1.1 本规范规定了C71000、C74500、C75200、C75700、C76400、C77000和C79200号UNS合金的圆形、六角形、八角形、矩形和方形导线的要求。 1.2 本规范是通用的，因为该产品在许多应用中使用，这些应用中的要求过于特殊，无法通过标准测试结果加以规定。 1.2.1 对于特殊或关键应用，建议买方向制造商提交样品或图纸，以确保对退火或回火进行调整，以适应产品的预期应用。 1.3 以下信息旨在帮助买方应用本规范: 1.3.1 对于大多数一般应用，UNS合金编号为C71000、C74500、C75200和C75700。 1.3.2 对于硬质或弹簧回火UNS合金C76400和C77000。 1.3.3 为了便于加工编号为C79200的UNS合金。 1.4 单位- 以英寸-磅单位或国际单位表示的数值应单独视为标准值。在本文中，国际单位制显示在括号中。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification establishes the requirements for wire in round, hexagonal, octagonal, rectangular, and square form of UNS Alloy Nos. C71000, C74500, C75200, C75700, C76400, C77000, and C79200. 1.2 This specification is general in that the product is used in many applications where the requirements are too particular to be specified by standard test results. 1.2.1 For particular or critical applications it is advisable for the purchaser to submit samples or drawings to the manufacturer to secure an adjustment of anneal or temper to suit the application for which the product is intended. 1.3 The following information is intended to assist the purchaser in the application of this specification: 1.3.1 For most general applications—UNS Alloy Nos. C71000, C74500, C75200, and C75700. 1.3.2 For hard or spring tempers—UNS Alloy Nos. C76400 and C77000. 1.3.3 For ease of machining—UNS Alloy No. C79200. 1.4 Units— Values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
