Brazing - Filler metals (ISO 17672:2024)
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.
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)
Le présent document spécifie les fourchettes 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 principal.
NOTE 1 Pour l'élément (les éléments) principal (aux), voir l'Annexe A.
En ce qui concerne les produits composites, tels que les baguettes de brasage enrobées, les pâtes ou les rubans plastiques, le présent document ne couvre que le métal d'apport faisant partie de tels produits. Les températures de fusion indiquées dans les tableaux ne sont qu'approximatives, étant donné qu'elles varient nécessairement dans les limites des fourchettes de composition du métal d'apport. Elles ne sont donc données qu'à titre informatif. Les conditions techniques de livraison sont données pour les métaux d'apport de brasage fort et pour les produits contenant des métaux d'apport de brasage fort, avec d'autres composants tels que des flux et/ou des liants.
NOTE 2 Pour certaines applications, tels que les métaux précieux en bijouterie, dans l'industrie aérospatiale et dentaire, des métaux d'apport autres que ceux mentionnés dans le présent document sont souvent utilisés. Ils sont couverts par d'autres Normes internationales auxquelles il peut être fait référence.

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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

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 International
Standard 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, e.g. precious metal jewellery, aerospace and dental, filler metals other than
those included in this International Standard are often used and these are covered by other International
Standards to which reference can be made.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 80000-1:2009, Quantities and units — Part 1: General
3 Terms and definitions
No terms and definitions are listed in this document.

— IEC Electropedia: available at https:// www .electropedia .org/
4 Composition
The filler metal shall have a composition in accordance with Tables 5 to 13 for the particular type,
except as modified for special vacuum requirements (see Clause 4 and Table 1).
If the values for an element range from 0 (—) to a defined value, the element may be, but does not have
to be, in that brazing filler metal.
For the purposes of determining compliance with composition limits, any value obtained from the
analysis shall be rounded to the same number of decimal places as used in this International Standard
in expressing the specified limit. The following rules shall be used for rounding.
a) When the figure immediately after the last figure to be retained is less than five, then the last figure
to be retained shall be kept unchanged.
ISO/DIS 17672:2023(E)
b) When the figure immediately after the last figure to be retained is either
1) greater than five, or
2) equal to five and followed by at least one figure other than zero,
the last figure to be retained shall be increased by one.
c) When the figure immediately after the last figure to be retained is equal to five, and followed by
zeros only, then the last figure to be retained shall be left unchanged if even and increased by one
if odd. For the purposes of determining compliance with the requirements of this International
Standard, the actual test values obtained shall be subjected to the rounding-off instructions given
in ISO 80000-1:2009, Annex B.
NOTE The chemical analysis is of the bulk material, but the material can be composed of discrete powders
with different individual compositions or multiple layers of roll-clad foils where each layer can have a different
individual composition.
5 Special vacuum requirement
In a few instances, which are most likely to apply to Ag 272, Pd 287, Pd 387, Pd 388, Pd 481, Pd 483,
Pd 484, Pd 587, Pd 647 and Au 295, Au 375, Au 625, Au 752, Au 801 and Au 827, lower impurity limits
can be required for brazing in vacuum or service in vacuum and these limits shall be as given in Table 1.
Filler metals complying with Table 1 shall have the letter V added as a suffix
