Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.

Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Web Shop at www.standards.com.au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue.

Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization.

We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover.

This Standard was issued in draft form for comment as DR 05342.

PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand

Committee, Welding Consumables, to supersede AS 1167.1—1993, Welding and brazing—

Filler metals, Part 1: Filler metal for brazing and braze welding.

The objective of this Standard is to specify requirements for brazing filler metal.

The main changes in this edition have been driven by the increasing international concern at

the risks of cadmium exposure and strategies at the global and Australian levels, and were

aimed at cadmium minimization. Hence, the deletion of nine alloys containing cadmium

(A4 to A7, A9 to A12 and A17) and the addition of six cadmium free alloys (A18 to A23)

in Table 1.

Other significant technical changes included the following:

(a) Deletion of alloys with very little usage (A1, A3, A13, A14 and B5).

(b) Reduction of cadmium impurity levels, in Tables 1 and 2, from 0.05 to 0.01%.

(c) Updating of melting ranges to show true liquidus values, and addition of Indicative

Brazing Temperature Ranges in Table 2.

(d) Deletion of alloy R4343 from Table 4, and updating Beryllium content from 0.0008%

to 0.0003% to align with ISO Standards.

In addition, Appendix A has been fully revised to update references to current equivalent

EN, AWS and ISO Standards.

Mechanical properties of brazed joints are not covered in this Standard but will generally be

found in the relevant application Standards.

The term ‘informative’ has been used in this Standard to define the application of the

appendix to which it applies. An ‘informative’ appendix is only for information and

guidance.

1 SCOPE

This Standard specifies requirements for filler metals in all forms for brazing and braze

welding processes. It includes requirements for chemical composition and analysis, packing

and marking. In addition, a standard form of colour coding designed to be mutually

acceptable to manufacturers and users has been recommended for identification purposes.

NOTE: In this Standard, the term brazing is used to imply both processes.

2 REFERENCED DOCUMENTS

Standards Australia

Standards Australia is an independent company, limited by guarantee, which prepares and publishes

most of the voluntary technical and commercial standards used in Australia. These standards are

developed through an open process of consultation and consensus, in which all interested parties are

invited to participate. Through a Memorandum of Understanding with the Commonwealth

government, Standards Australia is recognized as Australia’s peak national standards body.

Standards New Zealand

The first national Standards organization was created in New Zealand in 1932. The Standards

Council of New Zealand is the national authority responsible for the production of Standards.

Standards New Zealand is the trading arm of the Standards Council established under the Standards

Act 1988.

Australian/New Zealand Standards

Under a Memorandum of Understanding between Standards Australia and Standards New Zealand,

Australian/New Zealand Standards are prepared by committees of experts from industry,

governments, consumers and other sectors. The requirements or recommendations contained

in published Standards are a consensus of the views of representative interests and also take

account of comments received from other sources. They reflect the latest scientific and industry

experience. Australian/New Zealand Standards are kept under continuous review after publication

and are updated regularly to take account of changing technology.

International Involvement

Standards Australia and Standards New Zealand are responsible for ensuring that the Australian

and New Zealand viewpoints are considered in the formulation of international Standards and that

the latest international experience is incorporated in national and Joint Standards. This role is vital

in assisting local industry to compete in international markets. Both organizations are the national

members of ISO (the International Organization for Standardization) and IEC (the International

Electrotechnical Commission).
