ISO 17672:2024 钎焊 填充金属

标准编号：ISO 17672:2024

中文名称：钎焊 填充金属

英文名称：Brazing — Filler metals

发布日期：2024-04

标准范围

该文件规定了用于钎焊的一系列填充金属的组成范围。填充金属分为七类，与其成分有关，但不一定与存在的主要元素有关。笔记？1？关于存在的主要内容，见附件？A.在复合产品的情况下，例如涂有助焊剂的棒、糊或塑料带，本文件仅涵盖形成此类产品的部件的填充金属。表中给出的熔化温度只是近似的，因为它们必然在填充金属的组成范围内变化。因此，它们仅供参考。给出了钎焊填充金属和含有钎焊填充金属与其他成分如助焊剂和/或粘合剂的产品的技术交付条件。笔记？2？对于一些应用，例如贵金属首饰、航空航天和牙科，通常使用本文件中包括的填充金属以外的填充金属。这些都包含在可以参考的其他国际标准中。

This document specifies the compositional ranges of a series of filler metals used for brazing. The filler metals are divided into seven classes, related to their composition but not necessarily to the major element present.

NOTE 1        For the major element(s) present, see Annex A.

In the case of composite products, such as flux-coated rods, pastes or plastics tapes, this document covers only the filler metal that forms parts of such products. The melting temperatures given in the tables are only approximate, as they necessarily vary within the compositional range of the filler metal. Therefore, they are given only for information. Technical delivery conditions are given for brazing filler metals and products containing brazing filler metals with other constituents such as flux and/or binders.

NOTE 2        For some applications, such as precious metal jewellery, aerospace and dental, filler metals other than those included in this document are often used. These are covered by other International Standards to which reference can be made.
