1.1 这是目前可用于炼油厂形状和商业量锻造产品的各种铜类型的分类。它不是各种类型铜的规格。 1.2 在此分类中，使用了铜行业使用的标准铜名称。 1.3 尽管该分类包括实践中描述的某些UNS名称 E527型 ，这些名称仅供交叉参考，并非要求。因此，如有冲突，应以ASTM分类为准。 1.4 该分类并不试图区分所有可称为铜或铜基合金的成分，但根据行业的一般用途，包括铜和特定允许元素规定为99的铜。 85 % 除UNS C10100和C11040中银不被视为铜的情况外，银应视为铜。 注1: 铜可能含有少量特定元素，故意允许其赋予特定特性，而不会过度降低导电性。总铜和特定允许元素规定为99.85 % 或更多。这些故意允许的元素通常包括但不限于砷、镉、铬、铅、镁、银、硫、碲、锡、锌和锆，以及除氧剂，达到国际标准组织采用的特定水平。 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。 =====意义和用途====== 4.1 该分类列出了精炼厂或制造商提供的铜类型，或两者兼而有之，定义了常用术语，并给出了许多可用铜的特征。这对于寻找适合特定应用的合适铜的新手来说很有用。

1.1 This is a classification of the various types of copper currently available in refinery shapes and wrought products in commercial quantities. It is not a specification for the various types of copper. 1.2 In this classification, use is made of the standard copper designations in use by the copper industry. 1.3 Although this classification includes certain UNS designations as described in Practice E527 , these designations are for cross-reference only and are not requirements. Therefore, in case of conflict, this ASTM classification shall govern. 1.4 This classification does not attempt to differentiate between all compositions that could be termed either coppers or copper-base alloys, but in conformance with general usage in the trade, includes those coppers in which the copper plus specific permitted elements is specified as 99.85 % or more, silver being counted as copper except in the case of UNS C10100 and C11040 where silver is not counted as copper. Note 1: Coppers may contain small amounts of certain elements intentionally permitted to impart specific properties, without excessively lowering electrical conductivity. The total copper plus specific permitted elements is specified as 99.85 % or more. These intentionally permitted elements normally include, but are not limited to, arsenic, cadmium, chromium, lead, magnesium, silver, sulfur, tellurium, tin, zinc, and zirconium, plus deoxidizers, up to specific levels adopted by the International Standards Organization. 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. ====== Significance And Use ====== 4.1 This classification lists the types of copper available from refineries or fabricators, or both, defines the common terms used, and gives the characteristics of many of the coppers available. It is useful to the neophyte looking for the appropriate copper for a particular application.
