| 적용범위 | 1.1 This specification covers aluminum and aluminum alloy flat sheet, coiled sheet, and plate in the alloys (Note 1) and tempers shown in Tables 2 and 4, and in the following finishes: (A) Limits are in mass 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 right hand 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 non-conforming. 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. The total for other elements does not include vanadium. (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 1 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 for yield strength shall be rounded to the nearest 1 MPa 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) Elongations in 50 mm apply for thicknesses up through 12.50 mm and in 5× diameter for thicknesses over 12.50 mm. (D) Materials 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. (E) Tests of F temper plate for tensile properties are not required. (F) The tension test specimen from plate over 12.50 mm in thickness is machined from the core and does not include the cladding alloy. (G) This material is subject to some recrystallization and an attendant loss of brightness.
