1.1 This specification2 covers aluminum and aluminum-alloy flat sheet, coiled sheet, and plate in the alloys (Note 1) and tempers shown in Tables 2 and 3, and in the following finishes:
(A) Limits are in weight percent maximum unless shown as a range or stated otherwise.(B) Analysis shall be made for the elements for which limits are shown in this table.(C) For purposes of determining conformance to these limits, an observed value or a calculated value attained from analysis shall be rounded to the nearest unit in the last righthand place of figures used in expressing the specified limit, in accordance with the Rounding Method of Practice E29.(D) Others includes listed elements for which no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements not specified in the specification. However, such analysis is not required and may not cover all metallic Others elements. Should any analysis by the producer or the purchaser establish that an Others element exceeds the limit of Each or that the aggregate of several Others elements exceeds the limit of Total, the material shall be considered nonconforming. The Total for Other Elements does not include elements shown in the footnotes with specific composition limits.(E) Other Elements-Total shall be the sum of unspecified metallic elements, 0.010 % or more, rounded to the second decimal before determining the sum.(F) Vanadium 0.05 max.(G) The aluminum content shall be calculated by subtracting from 100.00 % the sum of all metallic elements present in amounts of 0.010 % or more each, rounded to the second decimal before determining the sum.(H) Composition of cladding alloy as applied during the course of manufacture. Samples from finished sheet or plate shall not be required to conform to these limits.(I) Vanadium 0.05-0.15, zirconium 0.10-0.25.(J) 0.05-0.25 Zr(K) Gallium 0.03 max, vanadium 0.05 max.(L) 0.10-0.6 Mn + Cr.(M) In case there is a discrepancy in the values listed in Table 2 with those listed in the "International Alloy Designations and Chemical Composition Limits for Wrought Aluminum and Wrought Aluminum Alloys" (known as the "Teal Sheets"), the composition limits registered with the Aluminum Association and published in the "Teal Sheets" shall be considered the controlling composition. The "Teal Sheets" are available at http://www.aluminum.org/tealsheets. (A) To determine conformance to this specification each value for tensile strength and yield strength shall be rounded to the nearest 0.1 ksi and each value for elongation to the nearest 0.5 %, both in accordance with the Rounding Method of Practice E29.(B) The basis for establishment of mechanical property limits is shown in Annex A1.(C) Material in either of these tempers (H32 or H22), (H34 or H24), (H36 or H26), (H38 or H28), (H12 or H22), (H14 or H24), (H16 or H26), (H18 or H28), may be supplied at the option of the supplier, unless one is specifically excluded by the contract or purchase order. When ordered as H2x tempers, the maximum tensile strength and minimum yield strength do not apply. When H2x tempers are supplied instead of ordered H1x or H3x tempers, the supplied H2x temper material shall meet the respective H1x or H3x temper tensile property limits.(D) Tests of F temper plate for tensile properties are not required.(E) The tension test specimen from plate 0.500 in. and thicker is machined from the core and does not include the cladding alloy.(F) This material is subject to some recrystallization and an attendant loss of brightness. (A) To determine conformance to this specification, each value for tensile strength and yield strength shall be rounded to the nearest 0.1 ksi and each value for elongation to the nearest 0.5 %, both in accordance with the Rounding Method of Practice E29.(B) The basis for establishment of mechanical property limits is shown in Annex A1.(C) Long transverse unless otherwise noted.(D) Coiled sheet.(E) Material in the T42, T62, and T72 tempers is not available from the material producer.(F) For stress-relieved tempers (T351, T451, T651, T7351, T7651, and T851), characteristics and properties other than those specified may differ somewhat from the corresponding characteristics and properties of material in the basic temper.(G) Test for tensile properties in the F temper are not required.(H) The tension test specimen from plate 0.500 in. and thicker is machined from the core and does not include the cladding.(I) Applicable to flat sheet and plate only.(J) The T72 temper is applicable only to Alloys 2024 and Alclad 2024 sheet solution heat treated and artificially overaged by the user to develop increased resistance to stress-corrosion cracking.(K) Short transverse tensile property limits are not applicable to material less than 1.500 in. in thickness.(L) Use of Alloys 2219 and Alclad 2219 in the T31, T351, and T37 tempers for finished products is not recommended.(M) The properties for this thickness apply only to the T651 temper.
1.1.1 Plate in all alloys and sheet in heat-treatable alloys: mill finish.
1.1.2 Sheet in nonheat-treatable alloys: mill finish, one-side bright mill finish, standard one-side bright finish, and standard two-sides bright finish.
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.
Note 1: Throughout this specification, use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 2: See Specification B632/B632M for tread plate.
Note 3: See Specification B928/B928M for 5xxx-H116 and 5xxx-H321 aluminum alloys containing 3 % or more nominal magnesium and intended for marine service and similar environments. Other alloy-temper products listed in this specification, which do not require the additional corrosion testing/capability called out in ASTM B928/B928M, may be suitable for marine and similar environment applications.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 This specification is the inch-pound companion to Specification B209M; therefore, no SI equivalents are presented in the specification.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
