Brazing - Filler metals (ISO 17672:2010)
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.
Hartlöten - Lötzusätze (ISO 17672:2010)
Diese Europäische Norm legt die Zusammensetzungen von Lotzusätzen fest, die zum Hartlöten verwendet
werden. Diese Lotzusätze sind entsprechend ihrer Zusammensetzung, aber nicht notwendigerweise nach dem
vorhandenen Hauptlegierungselement, in acht Gruppen aufgeteilt, siehe Anhang A. Diese Norm gilt nicht für
Produkte wie z. B. flussmittelummantelte Lotstäbe, Lotpasten oder -bänder, sondern nur für den Lotzusatz als
Anteil solcher Produkte. Obwohl in den Tabellen die Schmelzbereiche mit angegeben werden, können diese,
entsprechend der erlaubten Bandbreite der Zusammensetzung von Lotzusätzen variieren und gelten nur als
Näherungswerte. Deshalb sind die Schmelzbereichsangaben nicht Teil der Anforderungen und dienen nur zur
Information. Die technischen Lieferbedingungen gelten für Lotzusätze zum Hartlöten und für Produkte, die
Hartlote mit anderen Bestandteilen wie Flussmittel und/oder Umhüllung enthalten.
ANMERKUNG Für einige Anwendungen, z. B. Schmuckverarbeitung, Luft- und Raumfahrt und Zahntechnik, können
andere Lotzusätze als die, die in dieser Norm enthalten sind, verwendet werden. Diese Lotzusätze sind in anderen
Normen enthalten, auf die Bezug genommen werden kann.
Brasage fort - Métaux d'apport (ISO 17672:2010)
La présente Norme européenne spécifie les compositions chimiques d'une gamme de métaux d'apport utilisés pour le brasage fort. Les métaux d'apport ont été divisés en huit classes, d'apres leur composition chimique, mais pas nécessairement d'apres leur élément majeur, voir Annexe A. En ce qui concerne les produits composites, tels que les baguettes de brasage enrobées, les pâtes ou les rubans plastiques, la présente norme ne couvre que le métal d'apport faisant partie intégrante de tels produits. Bien que l'intervalle de fusion soit indiqué dans les tableaux, il varie nécessairement dans les limites des fourchettes de composition du métal d'apport et doit etre considéré comme approximatif. Il ne fait donc pas partie des présentes spécifications et n'est donné qu'a titre informatif. Les conditions techniques de livraison sont données pour les métaux d'apport de brasage fort et pour les produits contenant ces métaux d'apport de brasage fort, plus d'autres composants tels que des flux et/ou des liants.
NOTE Pour certaines applications, par exemple en bijouterie de métaux précieux, industrie aérospatiale et art dentaire, des métaux d'apport autres que ceux qui sont mentionnés dans la présente norme, sont souvent utilisés. Ces métaux d'apport sont couverts par d'autres normes auxquelles il convient de faire référence.
Trdo spajkanje - Dodajni materiali (ISO 17672:2010)

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.

---------------------- Page: 11 ----------------------
SIST EN ISO 17672:2011
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.

c
Except where otherwise specified in Tables 5 to 13.
d
Examples of such elements are Ca, Cs, K, Li, Mg, Na, Rb, S, Sb, Se, Sr, Te and Tl. For
such elements (including Cd, Pb and Zn), the total is limited to 0,010 %.
5 Chemical analysis
Chemical analyses shall be carried out by any suitable method, but it should be noted that in the case of many
brazing alloys, the use of reference standards may be essential, as agreed between the purchaser and the
supplier. Analysis is only required to be carried out routinely for those elements for which specific limits are
shown. If, however, the presence of other elements is suspected or in the course of routine analysis is
indicated to be in excess of the limits laid down for unnamed elements, or would bring the total of impurities
above the specified limit, further analyses shall be carried out for such elements.

6 Designation
The filler metal shall be designated by the description “filler metal”, the number of this International Standard,
i.e. ISO 17672, and a code. Details of the two options for the code system used are given in Annex A.
As an example, the designations of an aluminium filler metal containing 11 % to 13 % Si, in accordance with
this International Standard, can be made in one of the following ways:
EXAMPLE 1 Filler metal ISO 17672-Al 112
where
“Filler metal” is the description;
“ISO 17672” is the number of this International Standard;
“Al 112” is the short code given in Tables 5 to 13.
EXAMPLE 2 Filler metal ISO 17672-B-Al88Si-575/585
where
“Filler metal” is the description;
“ISO 17672” is the number of this International Standard;
“B” denotes brazing;
“Al88Si-575/585” is the code in accordance with ISO 3677.
7 Technical delivery conditions
7.1 Types of product
The form of the material shall be agreed between the purchaser and the manufacturer/supplier at the time of
placing the order.
NOTE Brazing filler metals are available as rod, wire, foil (or preforms made from them) or powder, although not all
filler metals are necessarily available in every type of product. They are also available as a constituent of brazing pastes or,
particularly in the case of aluminium brazing filler metals, clad onto one or both sides of an alloy sheet. Rods can be
completely or partially coated with flux.
7.2 Dimensions
7.2.1 General
Dimensions and tolerances for foils (see 7.2.2), rods (see 7.2.3) and, to a lesser extent, wires (see 7.2.4) are
defined. For other forms and dimensions not listed in the respective tables, the purchaser and the
manufacturer/supplier shall agree on the dimensions and tolerances at the time of placing the order.

7.2.3 Rods
For rods, the preferred diameters are 1 mm, 1,5 mm, 2 mm, 2,5 mm, 3 mm and 5 mm and the preferred
lengths are 500 mm and 1 000 mm. The tolerance on diameter shall be ± 3 % for drawn rods and ± 0,3 mm
for other fabrication processes. The tolerance on length shall be ± 5 mm.
7.2.4 Wires
For wires, there are no preferred diameters and the tolerance on diameter shall be ± 3 %.
7.3 Condition
The surface of brazing filler metals shall be free from contamination which could adversely affect brazing. With
flux-coated rods, the coating shall firmly adhere to the rod and shall not break off during proper handling and
usage. Welds, when present, shall have been made so as not to interfere with uniform, uninterrupted feeding
of filler metal on automatic and semiautomatic brazing.
7.4 Marking
Since in many cases the marking of brazing filler metals themselves is impracticable, reliance shall be placed
on the marking of packets. The outside of each smallest unit package shall be clearly marked with the
following information:
a) the designation in accordance with Clause 6;
b) the name of the manufacturer/supplier;
c) the trade name (if any);
d) the quantity of material and, if applicable, the dimensions;
e) the supplier's batch number;
f) health and safety warnings (as required by national regulations).
7.5 Packaging
Brazing filler metals or products containing them shall be packed to provide sufficient safeguard against
damage and deterioration during transportation and storage.
7.6 Product certificates
If certificates (like those specified in ISO 14344) of conformity and/or analysis are required, the purchaser and
the manufacturer/supplier shall agree on the details at the time of placing the order.
8 Metal hazards
Although not directly relevant to the requirements of this International Standard, any national requirements for
limiting exposure to metal hazards, e.g. fume, should be observed. This is particularly important when using
brazing filler metals containing cadmium as an alloying element.

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, Subcommittee
SC , and by Technical Committee CEN/TC 121, Welding in collaboration.

DRAFT INTERNATIONAL STANDARD ISO/DIS 17672
Brazing — Filler metals
1 Scope
This document specifies the compositions of a range of filler metals used for brazing. The filler metals have
been divided into seven classes, related to their composition but not necessarily to the major element present,
see annex A. In the case of composite products such as flux-coated rods, pastes or plastics tapes, the
standard only covers the filler metal that forms part of such products. Although the melting range is given in
the tables, it will necessarily vary within the compositional range of the filler metal and can only be regarded
as approximate. Therefore, it is not a part of the specification and is 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 For some applications, e.g. precious metal jewelry, aerospace and dental, filler metals other than those
included in this standard will often be used and these are covered by other standards to which reference should 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, Filler metal for soft soldering, brazing and braze welding — Designation
3 Composition
The filler metal shall have a composition in accordance with Tables 5 to 11 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 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;
then 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.

5 Chemical analysis
Chemical analyses shall be carried out by any suitable method, but it should be noted that in the case of many
brazing alloys, the use of reference standards may be essential, as agreed between the purchaser and
supplier. Analysis is only required to be carried out routinely for those elements for which specific limits are
shown. If, however, the presence of other elements is suspected, or in the course of routine analysis is
indicated, to be in excess of the limits laid down for unnamed elements or would bring the total of impurities
above the specified limit, further analyses shall be carried out for such elements.

6 Designation
The filler metal shall be designated by the description “filler metal”; the number of this standard “ISO 17672”
and a code. Details of the two options for the code system used are given in Annex A.
As an example, the designations of an aluminium filler metal containing 11 % to 13 % Si, in accordance with
this standard can be made in one of the following ways:
EXAMPLE 1 Filler metal ISO 17672-Al 112
where
“Filler metal” is the description
“ISO 17672” is the number of this standard
“Al 112” is the short code given in Tables 5 to 11
EXAMPLE 2 Filler metal ISO 17672-B-Al88Si-575/585
where
“Filler metal” is the description
“ISO 17672” is the number of this standard
“B” denotes brazing
“Al88Si-575/585” is the code in accordance with ISO 3677
7 Technical delivery conditions
7.1 Types of products
The form of the material shall be agreed between the purchaser and the manufacturer/supplier at the time of
placing the order.
NOTE Brazing filler metals are available as rod, wire, foil (or preforms made from them) or powder, although not all
filler metals are necessarily available in every type of product. They are also available as a constituent of brazing pastes or,
particularly in the case of aluminium brazing filler metals, clad onto one or both sides of an alloy sheet. Rods may be
completely or partially coated with flux.
7.2 Dimensions
7.2.1 General
Dimensions and tolerances for ribbon (see 7.2.2), rod (see 7.2.3) and to a lesser extent wire (see 7.2.4) are
defined, for other forms and dimensions not listed in the respective tables the dimensions and tolerances shall
be agreed between the purchaser and the manufacturer/supplier at the time of placing the order.

7.2.3 Rod
For rod the preferred diameters are 1 mm, 1,5 mm, 2 mm, 2,5 mm, 3 mm and 5 mm and the preferred lengths
are 500 mm and 1000 mm. The tolerance on diameter shall be ± 3% for drawn rod and ± 0,3 mm for other
fabrication processes. The tolerance on length shall be ± 5 mm.
7.2.4 Wire
For wire there are no preferred diameters and the tolerance on diameter shall be ± 3%.
7.3 Condition
The surface of brazing filler metals shall be free from contamination which could adversely affect brazing. With
flux-coated rods, the coating shall firmly adhere to the rod and shall not break off during proper handling and
usage. Welds when present, shall have been made so as not to interfere with uniform, uninterrupted feeding
of filler metal on automatic and semiautomatic brazing.
7.4 Marking
Since in many cases, marking of brazing filler metals themselves is impracticable, reliance shall be placed on
marking of packets. The outside of each smallest unit package shall be clearly marked with the following
information:
a) the designation in accordance with Clause 6;
b) the name of the manufacturer/supplier;
c) the trade name (if any);
d) the quantity of material and, as applicable, the dimensions;
e) the supplier's batch number;
f) health and safety warnings (as required by national regulations).
7.5 Packaging
Brazing filler metals or products containing them shall be packed to provide sufficient safeguard against
damage and deterioration during transportation and storage.
7.6 Product certificates
If certificates of conformity and/or analysis are required, details shall be agreed between the purchaser and
the manufacturer/supplier at the time of placing the order.
8 Metal hazards
Although not directly relevant to the requirements of this standard, it should be noted that any national
requirements for limiting exposure to metal hazards, e.g. fume must be observed. This is particularly important
when using brazing filler metals containing cadmium as an alloying element.
