1.1 本规范涵盖合金中的线材和棒材( 注1 )如表所示 1和表中所示的回火 2[表 3] 和表 4[表 5] ，适用于通过冷镦操作制造铆钉和其他类似物品。 注1: 在本规范中 合金 一般来说，包括铝以及铝合金。 注2: 有关轧制或冷加工的线材和棒材，请参阅规范 B211 ，挤压线材和棒材见规范 B221页 . 1.2 合金和回火名称符合ANSI H35.1/H35.1M。等效的统一编号系统合金名称如下表所示 1前面有A9，例如，A91100用于铝1100，符合惯例 E527 . 1.3 有关本规范中包含新铝和铝合金的验收标准，请参阅 附件A2 . 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。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。 1.4.1 国际单位制显示在括号中或单独的表格中。 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 covers wire and rod in the alloys ( Note 1 ) shown in Table 1 and the tempers shown in Table 2 [Table 3] and Table 4 [Table 5], suitable for manufacturing rivets and other similar items by cold-heading operations. Note 1: Throughout this specification the use of the term alloy in the general sense includes aluminum as well as aluminum alloy. Note 2: For rolled or cold-finished wire and rod, see Specification B211 , and for extruded wire and rod, see Specification B221 . 1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527 . 1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2 . 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard. 1.4.1 The SI units are shown either in brackets or in separate tables. 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.
