Brazing - Filler metals (ISO 17672:2010)
ISO 17672:2010 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.
In the case of composite products, such as flux-coated rods, pastes or plastics tapes, ISO 17672:2010 covers only the filler metal that forms part of such products.
Hartlöten - Lote (ISO 17672:2010)
Diese Internationale Norm 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.
Diese Internationale Norm gilt nicht für Produkte wie z. B. flussmittelummantelte Lotstäbe, Lotpasten
oder -bänder, sondern nur für den Lotanteil solcher Produkte. Obwohl in den Tabellen die Schmelzbereiche mit
angegeben werden, können diese, entsprechend der erlaubten Bandbreite der Zusammensetzung von Loten
variieren und gelten nur als Näherungswerte. 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, können
andere Lote als die, die in dieser Norm enthalten sind, verwendet werden. Diese Lote sind in anderen Internationalen
Normen enthalten, auf die Bezug genommen werden kann.
Brasage fort - Métaux d’apport (ISO 17672:2010)
L'ISO 17672:2010 spécifie les gammes de composition de métaux d'apport utilisés pour le brasage fort. Les métaux d'apport ont été divisés en sept classes, d'après leur composition, mais pas nécessairement d'après leur élément majeur.
En ce qui concerne les produits composites, tels que les baguettes de brasage enrobées, les pâtes ou les rubans plastiques, l'ISO 17672:2010 ne couvre que le métal d'apport faisant partie intégrante de tels produits.
Trdo spajkanje - Dodajni materiali (ISO 17672:2010)
Ta mednarodni standard določa razpone sestave vrste dodajnih materialov, ki se uporabljajo za trdo spajkanje. Dodajni materiali so glede na sestavo, a ne nujno glede na glavni prisotni element, razdeljeni v sedem razredov.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 17672 was prepared by Technical Committee ISO/TC 44, Welding and allied processes.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/WG 3 via your national standards body, a complete listing which can be found at

INTERNATIONAL STANDARD ISO 17672:2010(E)
Brazing — Filler metals
1 Scope
This International Standard 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 part 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 referenced documents are indispensable for the application 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 3677:1992, Filler metal for soft soldering, brazing and braze welding — Designation
ISO 80000-1:2009, Quantities and units — Part 1: General
3 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).
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.
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.
ISO 17672:2010(E)
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.
4 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 to the codification plus the digit 1
or 2 to indicate the grade.
NOTE Grade 1 is intended for the most demanding duties, Grade 2 for less demanding.
