1.1 本规范规定了用于拉伸、成形、冲压、弯曲和一般工程应用以及压力容器应用的铜硅合金板、薄板、带材和轧制棒材的要求。涉及的合金为铜合金UNS编号C65100、C65400和C65500。 1.2 订购产品时 ASME锅炉及压力容器规范 应用程序，请参阅代码 2. 适用合金。 1.3 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不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.4 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 copper-silicon alloy plate, sheet, strip, and rolled bar for drawing, forming, stamping, bending, and general engineering applications, and for pressure vessel applications. The alloys involved are copper alloys UNS Nos. C65100, C65400, and C65500. 1.2 When product is ordered for ASME Boiler and Pressure Vessel Code applications, consult the Code 2 for applicable alloys. 1.3 Units— The 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 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.
