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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
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, Subcommittee
SC 3, Welding consumables.
This second edition cancels and replaces the first edition (ISO 18273:2004), which has been
technically revised.
Requests for official interpretations of any aspect of this International Standard should be directed to

ISO 18273:2015(E)
Introduction
For aluminium welding consumables, there is no unique relationship between the product form (solid
wire or rod) and the welding process used (e.g. gas shielded metal arc welding, gas tungsten arc
welding, plasma arc welding, or other welding processes). For this reason, the solid wires or rods can be
classified on the basis of any of the above product forms and can be used as appropriate for more than
one of the above processes.
INTERNATIONAL STANDARD ISO 18273:2015(E)
Welding consumables — Wire electrodes, wires and
rods for welding of aluminium and aluminium alloys —
Classification
1 Scope
This International Standard specifies requirements for classification of solid wires and rods for fusion
welding of aluminium and aluminium alloys. The classification of the solid wires and rods is based on
their chemical composition.
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 544, Welding consumables — Technical delivery conditions for filler materials and fluxes — Type of
product, dimensions, tolerances and markings
ISO 14344, Welding consumables — Procurement of filler materials and fluxes
ISO 80000-1:2009, Quantities and units — Part 1: General. Corrected by ISO 80000-1:2009/Cor 1:2011
3 Classification
The classification is divided into two parts.
a) The first part indicates the product form being solid wires or rods (see 4.1).
b) The second part gives a numerical symbol indicating the chemical composition of the solid wire or
rod (see Table 1).
The aluminium or aluminium alloy chemical composition limits specified are strictly identical to those
registered to the Aluminium Association, Washington, DC 20006, U.S.A. for the corresponding alloys.
