Brazing - Filler metals (ISO 17672:2024)
ISO 17672:2016 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.
Hartlöten - Lote (ISO 17672:2024)
Dieses Dokument legt die Zusammensetzungen von Loten fest, die zum Hartlöten verwendet werden. Diese Lote sind entsprechend ihrer Zusammensetzung, aber nicht notwendigerweise nach dem vorhandenen Hauptlegierungselement, in sieben Gruppen aufgeteilt.
ANMERKUNG 1 Für die Hauptlegierungselemente, siehe Anhang A.
Im Falle von Verbundwerkstoffen, wie z. B. flussmittelummantelte Lotstäbe, Lotpasten oder -bänder, ist dieses Dokument nur für den Lotanteil solcher Produkte anwendbar. Die in den Tabellen angegebenen Schmelztemperaturen sind nur Näherungswerte, da sie entsprechend der erlaubten Bandbreite der Zusammensetzung der Lote zwangsläufig variieren. Deshalb dienen diese Angaben nur zur Information. Die technischen Lieferbedingungen gelten für Lote zum Hartlöten und für Produkte, die Hartlote mit anderen Bestandteilen wie Flussmittel und/oder Umhüllung enthalten.
ANMERKUNG 2 Für einige Anwendungen, z. B. Schmuckverarbeitung, Luft- und Raumfahrt und Zahntechnik, werden oft andere Lote als die, die in diesem Dokument enthalten sind, verwendet. Diese Lote sind in anderen Internationalen Normen enthalten, auf die Bezug genommen werden kann.
Brasage fort - Métaux d'apport (ISO 17672:2024)
ISO 17672:2016 spécifie les gammes de composition d'une série de métaux d'apport utilisés pour le brasage fort. Les métaux d'apport sont divisés en sept classes, d'après leur composition, mais pas nécessairement d'après leur élément majeur présent.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 13, Brazing materials and processes, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 121, Welding and allied processes, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 17672:2016), which has been technically
revised.
The main changes are as follows:
— in Clause 6, the spatter test was added;
— in 8.2.2, a NOTE on foils with a width of less than 3 mm was added;
— in Table 6, four new silver brazing filler metals were added;
— in Table 7, the range of Si was changed to 0,01 up to 0,25 (mass fraction %) if intentionally added;
— in Table 11, two new Ni-Cr-P-Si alloys were added;
— in Table A.1, the codes were updated and corresponding GB codes were added.

Brazing — Filler metals
1 Scope
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
