18、YRIGHT DIN DEUTSCHES Institut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 3 EN 573-2 : 1994 1 scope This Part of EN 573 specifies a code of designation applicable to aluminium and aluminium alloys as specified in the relevant European Standards. It is a descriptive code ba

19、sed primarily on chemical symbols. The designations in accordance with this Part of EN 573 are intended primarily as a supplement to the four figure designation described in EN 573-1. This standard applies to wrought products and to ingots intended to be wrought. It is not applicable to : - ingots f

20、or remelting ; - castings ; - composite proucts, i.e. those containing, in addition to aluminium and its alloys, other metaiiic or non-metallic materials ; - products of powder metallurgy. 2 Nonnative references This European Standard incorporates by dated or undated reference, provisions from other

21、 publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or r

22、evision. For undated references the latest edition of the publication referred to applies.

IS0 209-1 1989 Wrought aluminium and aluminium alloys - Chemical composition and fonns of products - Part 1 : Chemical composition. 3 Basis of coding 3.1 The designations of aluminium and aluminium alloys are based on the chemical symbols, usually foll

24、owed by numbers indicating the punty of aluminium or nominal content of the considered element. COPYRIGHT DIN DEUTSCHES Institut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 4 EN 573-2 : 1994 3.2 The chemical symbols used are those of the international nomenclature (see ann

25、ex A). 3.3 The numbers or figures indicating the purity of aluminium, or the nominal content of the considered element, are based on the chemical composition limits given in EN 573-3. 3.4 Normally all designations complying with this coding shall be put within square brackets, following the four fig

26、ure designation. If, exceptionally, only the chemical symbol based designation is used, then it shall have the prefix EN, followed by a blank, then the letter A representing aluminium and the letter W dentQing wrought products (and ingots to be wrought). The letter W shall be separated from the foll

27、owing designation by a hyphen. EXAMPLES : Normal use : EN AW-5052 or EN AW-5052 AI Mg2.51 Exceptional use : EN AW-AI Mg2,5 3.5 The designations currently in use and the corresponding chemical composition limits are specified in EN 573-3. 3.6 Assignments or revisions of designations shall be approved

28、 by Technical Committee CENlTCl32. 3.7 In order to ensure consistency with other national and international standards, and in particular with IS0 209-1 : 1989 whose code of designation is based on the same principles : - where the composition of an alloy is strictly identical to the composition of a

29、n alloy registered by ISO, the IS0 designation shall be used ; - where the composition of an alloy does not correspond to the composition of any alloy in IS0 209-1 : 1989, CENTTC 132 will create a new designation for this alloy, and keep ISO/TC 79 infonned. 4 Rules for the coded designation of wroug

30、ht unalloyed aluminium Designations for unalloyed aluminium for working shall consist of the intemational chemical symbol of the metal (AI) followed by the percentage punty expressed to one or more decimal places, as necessary. EXAMPLES EN AW-1199 Al 99,991 EN AW-107OA Al 99,7 COPYRIGHT DIN DEUTSCHE

31、S Institut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 5 EN 573-2 : 1994 The symbol AI is separated by a blank space from the percentage punty. If an element is added to unalloyed aluminium at a low content, the symbol corresponding to this element shall be added without a

32、 space after the percentage punty. EXAMPLE EN AW-11 O0 AI 99,OCuJ 5 Rules for the coded designation of wrought aluminium alloys 5.1 Basic principles 5.1.1 An alloy is designated by AI, followed by the symbols of the main alloying element or elements. These symbols are usually followed by numbers whi

33、ch express the mass percent contents of the considered elements, in compliance with the rules shown in 5.2. The symbol AI is separated by a blank space from the remainder of the designation. 5.1.2 Where several alloying elements are deemed to be required in the designation, they are arranged in orde

34、r of decreasing nominal contents. EXAMPLES : EN AW-6061 AI MglSiCu EN AW-2014 AI Cu4SiMgJ 5.1.3 If these contents are equal, the alloying elements are arranged in alphabetical order of the symbols. EXAMPLE : EN AW-2011 Al CuGBiPb 5.1.4 The chemical symbols for alloying elements shall be restricted t

35、o four elements. EXAMPLE : EN AW-7050 Al ZnGCuMgZrJ 5.2 Rules for distinguishing btween two alloys of similar compositions 5.2.1 Care shall be taken to use the simplest possible designation In the case of alloys with similar compositions, additional designations shall be used for distinguishing betw

36、een alloys. They are given, in decreasing priority, in 5.2.2 to 5.2.4. 5.2.2 The primary alloying element shall be distinguished by the nominal content (middle of the range) rounded to the nearest integer or, if necessary, to the nearest 5/10, or for contents less than 1 %, to the nearest 1/10.

38、to the nearest integer of, if necessary, to the nearest 5/10, or, for contents less than 1 %, to the nearest 1/10. EXAMPLES : EN AW-3103 AI Mnl EN AW-3005 Al MnlMg0,5 EN AW-3004 AI MnlMgl 5.2.4 If the above provisions are not sufficient for differentiating between several alloys, a suffix shall be u

39、sed : (A), (B), (C), etc, according to the date of submission to CEN ; the first alloy submitted has no suffix. This suffix shall be placed in parentheses to avoid confusion with the chemical symbols. EXAMPLES EN AW-2014 Al CMSiMg EN AW-2014A AI CU4SiMg(A) 6 Special use of grades of wrought aluminiu

40、m and aluminium alloys This practice shall be restricted as far as possible. It shall be limited to the case where the considered application requires specific chemical composition limits for at least one element. A letter introducing the chemical composition can then be used . The letter E has been

41、 allocated to electrical applications. EXAMPLES : EN AW-1350 Ut 99.5) electrical applications EN AW-6101 EAI MgSi electrical applications EN AW-105OA Al 99.51 general applications 7 Alloys produced from high purity aluminium In certain alloys, the base metal is of high purity, for example AI 99,85 %
