1、Designation: B275 05 (Reapproved 2013)Standard Practice forCodification of Certain Nonferrous Metals and Alloys, Castand Wrought1This standard is issued under the fixed designation B275; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisi

2、on, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This practice covers

3、 a system originally adopted fordesignating light metals and alloys, cast and wrought, and laterextended to certain heavier, base-metal die-casting alloys.Those designations, which are currently being used in specifi-cations under the jurisdiction of Committees B02 on Nonfer-rous Metals and Alloys a

4、nd B07 on Light Metals and Alloys,are listed in Table X2.1.1.1.1 The alloy designations now being used in CommitteeB07 specifications for aluminum and aluminum-alloy wroughtand cast products conform to ANSI H35.1. Alloys formerlycodified by this practice and the corresponding ANSI designa-tions are

5、shown in Tables X3.1 and X3.2.1.2 This practice also provides a system for designatingmagnesium alloys that have been used commercially since1952, and thus is intended to be the registration source for newmagnesium alloys. A record of designations along with theestablished compositions is given in T

United States13.3 The temper designation, which is used for all metalforms, except ingot, follows the alloy designa

16、tion and isseparated with a dash.4. Alloys4.1 Designation for alloys shall consist of not more than twoletters representing the alloying elements (Note 2) specified inthe greatest amount, arranged in order of decreasingpercentages, or in alphabetical order if of equal percentages,followed by the res

17、pective percentages rounded off to wholenumbers and a serial letter (Notes 3 and 4). The full name ofthe base metal precedes the designation, but it is omitted forbrevity when the base metal being referred to is obvious.NOTE 2For codification, an alloying element is defined as an element(other than

18、the base metal) having a minimum content greater than zeroeither directly specified or computed in accordance with the percentagesspecified.NOTE 3The serial letter is arbitrarily assigned in alphabetical se-quence starting with “A” (omitting “I” and “O”) and serves to differentiateotherwise identica

19、l designations. A serial letter is necessary to completeeach designation.NOTE 4The designation of a casting alloy in ingot form is derivedfrom the composition specified for the corresponding alloy in the form ofcastings. Thus, a casting ingot designation may consist of an alloydesignation having one

20、 or more serial letters, one for each productcomposition, or it may consist of one or more alloy designations.4.2 The letters used to represent alloying elements shall bethose in Table 1.4.3 In rounding percentages, the nearest whole number shallbe used. If two choices are possible as when the decim

21、al isfollowed by a 5 only, or a 5 followed only by zeros, the nearesteven whole number shall be used.4.4 When a range is specified for the alloying element, therounded mean shall be used in the designation.4.5 When only a minimum percentage is specified for thealloying element, the rounded minimum p

22、ercentage shall beused in the designation.5. Unalloyed Metals5.1 Designations for unalloyed metals consist of the speci-fied minimum purity, all digits retained but dropping thedecimal point, followed by a serial letter (Note 3). The fullname of the base metal precedes the designation, but it isomit

23、ted for brevity when the base metal being referred to isobvious.6. Keywords6.1 aluminum; lead; magnesium; tin; UNS designations;zincAPPENDIXES(Nonmandatory Information)X1. EXAMPLES OF CODIFICATIONX1.1 Example 1For Alloy CG181A in SpecificationB327, “C” represents copper, the alloying element specifi

25、 thefirst alloy qualified and assigned under the designation CG181.X1.2 Example 2For Alloys AZ91A, B, and C, in Speci-fication B93/B93M, “A” represents aluminum, the alloyingelement specified in the greatest amount; “Z” represents zinc,the alloying element specified in the second greatest amount;“9”

26、 indicates that the rounded mean aluminum percentage liesbetween 8.6 and 9.4; “1” signifies that the rounded mean of thezinc lies between 0.6 and 1.4; and “A” as the final letterindicates that this is the first alloy whose composition qualifiedassignment of the designation AZ91. The final serial let

27、ters Band C signify alloys subsequently developed whose specifiedcompositions differ slightly from the first and from one anotherbut do not differ sufficiently to effect a change in the basicdesignation.TABLE 1 Letters Representing Alloying ElementsAAluminum NNickelBBismuth PLeadCCopper QSilverDCadm
