13、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 esta
14、blished 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 standardiza
15、tion. 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 votin
16、g. 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
17、patent rights. ISO 2107 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 9, Symbolization. This third edition cancels and replaces the second edition (ISO 2107:2004), which has been technically revised by the addition of a terms and definitions clause and
18、 the designation of solution heat-treatment. This edition deals with wrought aluminium products and no longer applies to magnesium alloys.

20、s required for identification for all product forms of wrought aluminium and aluminium alloys. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 temper condition produced by either mechanical or thermal treatment, or both, and characterized by
21、a certain structure and mechanical properties 2.2 working deformation of metal, either hot or cold, by shaping processes including rolling, extruding, forging, drawing 2.3 hot working plastic deformation, i.e., permanent deformation of metal at such temperatures that no strain-hardening occurs 2.4 c
22、old working plastic deformation, i.e., permanent deformation of metal at such temperatures that strain-hardening occurs 2.5 strain-hardening modification of a metal structure, by cold working, resulting in an increase in strength and hardness but with loss of ductility 2.6 solution heat-treating hea

26、ication The temper designations are based on the sequences of basic treatments used to produce the various tempers. Property limits (mechanical or physical) apply to individual alloy-temper-product combinations. The temper designation follows the alloy designation; these are separated by a hyphen. B
27、asic temper designations consist of letters. If subdivisions of the basic tempers are required, these are indicated by one or more digits following the letter of the basic temper. These digits relate to a specific sequence of basic treatments, but only those treatments or operations recognized as si
28、gnificantly influencing the product characteristics are indicated. Should some other variation of the same sequence of basic operations be applied to the same alloy, resulting in different characteristics, then additional digits are added to the designation. Throughout this International Standard, g
29、eneralized examples of tempers are shown, as follows: “X” denotes an unspecified digit (e.g., H2X is generalized to indicate appropriate temper designations in the series H21 to H29); “XX” denotes two unspecified digits (e.g., HXX4 is generalized to indicate appropriate temper designations in the H1
30、14 to H194 series, the H224 to H294 series, and the H324 to H394 series); “_” denotes one or multiple unspecified digits (e.g., T_51 is generalized to indicate appropriate temper designations such as T351, T651, T6151, T7351, T7651, etc.). 4 Basic temper designations 4.1 F as fabricated This designa
31、tion applies to the products of shaping processes in which no special control over thermal conditions or strain-hardening is applied. For this temper, there are no mechanical property limits specified. 4.2 O annealed This designation applies to wrought products that are annealed to obtain the lowest
32、 strength temper, and to cast products that are annealed to improve ductility and dimensional stability. The O may be followed by a digit other than zero1) to indicate a product in the annealed condition having special characteristics. 4.3 H strain-hardened This designation applies to products subje
33、cted to the application of cold work after annealing (or after hot forming), or to a combination of cold work and partial annealing or stabilizing, in order to achieve the specified mechanical properties. The letter H is always followed by at least two digits, the first indicating the specific combi
34、nation of basic operations and the second indicating the degree of strain hardening. A third digit indicates a variation of a two digit temper and is used when the mechanical properties, or other characteristics, differ from those of the two-digit H temper to which it is added. 4.4 W solution heat-t
35、reated This designation describes an unstable temper. It applies only to alloys which spontaneously age at room temperature after solution heat-treatment. This designation is specific only when the period of natural ageing is indicated, e.g., W 1/2 h. 1) Products achieving the required annealed prop
36、erties after hot forming processes may be designated as O temper.

The T is always follow
38、ed by one or more digits indicating the specific sequence of treatments. 5 Subdivisions of O temper designations 5.1 O1 high-temperature annealed and slow cooled This designation applies to wrought products that are thermally treated at approximately the same time and temperature required for soluti
39、on heat-treatment and slow cooled to room temperature in order to accentuate ultrasonic response and/or to provide dimensional stability. It is applicable to products that are to be machined prior to solution heat-treatment by the user. Mechanical property limits are not specified. 5.2 O2 thermo-mec
40、hanically processed This designation applies to wrought products subjected to a special thermo-mechanical treatment. It is applicable to products which are to be super-plastically formed prior to solution heat-treatment by the user. 5.3 O3 homogenized This designation applies to continuously cast dr
41、awing stock or strip which is subjected to a high-temperature thermal treatment to eliminate or reduce segregation, thus improving subsequent formability and/or response to solution heat-treatment. 6 Subdivisions of H temper designations 6.1 General Subdivisions are made according to the basic opera
42、tions described in Clause 4 and the final degree of strain hardening as described in 6.2 to 6.5. 6.2 First digit after H The first digit following the letter H indicates the specific combination of basic operations as follows: a) H1X Strain-hardened only These designations apply to products that are
43、 strain-hardened to obtain the desired strength without supplementary thermal treatment. b) H2X Strain-hardened and partially annealed These designations apply to products that are strain-hardened more than the desired final amount, and then reduced in strength to the desired level by partial anneal
44、ing. For alloys that age-soften at room temperature, the H2X tempers have the same minimum ultimate tensile strength as the corresponding H3X tempers. For other alloys, the H2X tempers have the same minimum ultimate tensile strength as the corresponding H1X tempers and slightly higher elongation. c)
45、 H3X Strain-hardened and stabilized These designations apply to products that are strain-hardened and whose mechanical properties are stabilized either by a low-temperature thermal treatment or as a result of heat introduced during fabrication. Stabilization usually improves ductility. This designat
46、ion is applicable only to those alloys which, unless stabilized, gradually age-soften at room temperature.
