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 of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

.org/iso/foreword .html.

This document was prepared by Technical Committee ISO/TC 79, Light metals and their alloys,

Subcommittee SC 5, Magnesium and alloys of cast or wrought magnesium.

This fifth edition cancels and replaces the fourth edition (ISO 3116:2007), which has been technically

revised to include wrought magnesium alloys that have been developed in the past few years.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/members .html.

Magnesium and magnesium alloys — Wrought magnesium
and magnesium alloys
1 Scope

This document specifies the chemical composition and mechanical properties of magnesium and

magnesium alloys for wrought products in the form of bars and solid sections, tubes and hollow

sections, forgings, and plate and sheet.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements 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 80000-1:2009, Quantities and units — Part 1: General

ISO 6892-1, Metallic materials — Tensile testing — Part 1: Method of test at room temperature

EN 515, Aluminium and aluminium alloys — Wrought products — Temper designations
3 Terms and definitions
No terms and definitions are listed in this document.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https: //www .iso .org/obp

4 Designation
4.1 Material
The material shall be designated by symbols as given in Tables 1 to 47.

The designation for alloys shall consist of a prefix character “M”, which represents magnesium, and not

more than three capital letters representing the alloying elements specified in the greatest amount,

arranged in order of decreasing percentages, or in alphabetical order if of equal percentages, followed

by the respective percentages rounded off to whole numbers and a serial letter in lower case.

The letters used to represent the alloying elements shall be those in Table 1. The third letter is used when

the third largest amount of element is above or equal to 1 wt.%. If the third and fourth largest amount

of elements are above or equal to 1, the higher amount of elements is taken; if of equal percentage, the

third letter is decided by the producer who developed the alloy.
© ISO 2019 – All rights reserved 1
---------------------- Page: 6 ----------------------
ISO 3116:2019(E)
Table 1 — Letters representing alloying elements
Letters Element Name of element Letters Element Name of element
A Al Aluminium N Ni Nickel
B Bi Bismuth P Pb Lead
C Cu Copper Q Ag Silver
D Cd Cadmium R Cr Chromium
E RE Rare Earth S Si Silicon
F Fe Iron T Sn Tin
H Th Thorium V Gd Gadolinium
J Sr Strontium W Y Yttrium
K Zr Zirconium X Ca Calcium
L Li Lithium Y Sb Antimony
M Mn Manganese Z Zn Zinc

In rounding percentages, the nearest whole number shall be used. If two choices are possible, for

example when the decimal is followed by a 5 only or a 5 followed only by zeros, the nearest even whole

number shall be used. When a range is specified for the alloying element, the rounded mean shall be

used in the designation. When only a minimum percentage is specified for the alloying element, the

rounded minimum percentage shall be used in the designation. For example:
— an aluminium content of 1,2 wt.% is written as A1;
— an aluminium content of 1,5 wt.% is written as A2;
— an aluminium content of 2,5 wt.% to 3,6 wt.% is written as A3;
— an aluminium content of 2,5 wt.% is written as A2.

The serial letter is defined as “a” or “b” when the two compositions have only minor difference.

For example, ISO-MgAl3Zn1(A) is designated as MAZ31a and ISO-MgAl9Ca1Zn1 is designated as

MAXZ911.

A list of national designations corresponding to this document is given in Annex A. A table of physical

properties of the listed alloys is given in Annex B.
4.2 Temper designation
The following symbols shall be used for temper designation:
— O: annealed;
— F: as fabricated;

— H × 8: fully hardened (stain hardened to give maximum ultimate tensile strength);

— H × 4: half hardened (stain hardened to give an ultimate tensile strength approximately midway

between that of annealed and H × 8 temper);

— H × 2: quarter hardened (stain hardened to give an ultimate tensile strength approximately midway

between that of annealed and H × 4 temper);

— H112: Strain hardened from working at elevated temperature or from a limited amount of cold

work, and for which there are mechanical properties limits.

— T5: cooled from an elevated temperature shaping process and then artificially aged;

— T6: solution heat treated and then artificially aged.

4.3 Designations of product form
The following symbols shall be used for product form:
— B: bars and solid sections;
— T: tubes and hollow sections;
— F: forgings;
— P: plate and sheet.
4.4 Designation for ordering
