1.1 本规范涵盖锌和锡合金线，包括锌铝、锌铝铜、锌锡、锌锡铜和锡锌，用于电子行业的热喷涂线。 1.1.1 本标准中规定的某些合金也用作焊料，用于在低于熔点的温度下将两种或两种以上金属连接在一起，以及用于其他目的（如 附件A1 ). 规格 B907 涵盖用作焊料的锌、锡和镉基合金，其主要用于在低于熔点的温度下将两种或两种以上金属连接在一起以及用于其他目的（如规范附件部分所述） B907 ). 规格 B833 覆盖主要用于钢防腐的热喷涂（金属化）用锌和锌合金线（如规范附件部分所述 B833 ). 1.1.2 本规范包括锡基合金，因为其在电子工业中的使用类似于某些锌合金的使用，但不同于规范中规定的锡和铅焊料成分的主要用途 B32 . 1.1.3 这些金属丝合金的标称液相线温度不超过850℃ 华氏度（455 °C）。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 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 covers zinc and tin alloy wire, including zinc-aluminum, zinc-aluminum-copper, zinc-tin, zinc-tin-copper and tin-zinc, used as thermal spray wire in the electronics industry. 1.1.1 Certain alloys specified in this standard are also used as solders for the purpose of joining together two or more metals at temperatures below their melting points, and for other purposes (as noted in Annex A1 ). Specification B907 covers Zinc, Tin and Cadmium Base Alloys Used as Solders which are used primarily for the purpose of joining together two or more metals at temperatures below their melting points and for other purposes (as noted in the Annex part of Specification B907 ). Specification B833 covers Zinc and Zinc Alloy Wire for Thermal Spraying (Metallizing) used primarily for the corrosion protection of steel (as noted in the Annex part of Specification B833 ). 1.1.2 Tin base alloys are included in this specification because their use in the electronics industry is similar to the use of certain zinc alloys but different than the major use of the tin and lead solder compositions specified in Specification B32 . 1.1.3 These wire alloys have a nominal liquidus temperature not exceeding 850 °F (455 °C). 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 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.
