Brazing - Filler metals (ISO 17672:2016)
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.

Brasage fort - Métaux d'apport (ISO 17672:2016)
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.
Trdo spajkanje - Dodajni materiali (ISO 17672:2016)
Ta mednarodni standard določa sestavne obsege nabora dodajnih materialov, ki se uporabljajo za
trdo spajkanje. Dodajni materiali so razdeljeni v sedem razredov glede na sestavo, vendar ne nujno glede na prisotni glavni element.
OPOMBA 1: Za glavne elemente glej dodatek A.
Pri kompozitnih proizvodih, kot so palice, prevlečene s talilom, paste ali polimerni trakovi, ta mednarodni standard zajema samo dodajni material, ki tvori dele takšnih proizvodov. Temperature taljenja, ki so podane v preglednicah, so samo približne, saj se razlikujejo glede na sestavo dodajnega materiala. Zato so samo informativne narave. Tehnični dobavni pogoji so podani za dodajni material za trdo spajkanje in proizvode, ki vsebujejo dodajni material za trdo spajkanje z drugimi sestavnimi elementi, kor so talila in/ali veziva.
OPOMBA 2: Pri nekaterih načinih uporabe, npr. nakit iz plemenitih kovin, aeronavtika in zobozdravstvo, se pogosto uporabljajo dodajni materiali, ki niso vključeni v ta mednarodni standard. Ti so obravnavani v drugih mednarodnih standardih, na katere se lahko sklicujejo.

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
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 44, Welding and allied processes.
This second edition cancels and replaces the first edition (ISO 17672:2010), which has been technically
revised.
Requests for official interpretations of any aspect of this International Standard should be directed to

INTERNATIONAL STANDARD ISO 17672:2016(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 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, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 3677, Filler metal for soft soldering 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).
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.
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 l
