This specification covers aluminum and aluminum-alloy drawn seamless tubes in straight lengths and coils for general purpose. The tube shall be produced by drawing an extruded tube made from hollow extrusion ingot (cast in hollow form or pierced) and extruded by the use of the die and mandrel method. The tubes shall conform to the chemical composition requirements specified. The determination of chemical composition shall be made in accordance with suitable chemical (test methods E 34), or spectrochemical (test methods E 607 and E 1251), methods. The tube shall conform to the tensile property requirements specified. The tension tests shall be made in accordance with test methods B 557M. Flattening test specimens shall be flattened sidewise under a gradually applied load so as to give a uniform radius of bend until the minimum outside diameter under load is not more than F times the wall thickness of the tube as specified. The specimen shall be forced axially with steady pressure over a hardened and polished tapered steel pin having a 74? included angle, to produce a flare having the permanent expanded outside diameter specified. When specified, heat treatment of applicable tempers shall be in accordance with practice B 918. The different methods for leak testing of tubes are presented.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers aluminum and aluminum-alloy drawn seamless tubes in straight lengths and coils for general purpose and pressure applications in alloys (Note 2), tempers, and thicknesses shown in Table 2. Coiled tubes are generally available only as round tubes with a wall thickness not exceeding 0.083 in. and only in nonheat-treatable alloys.

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 designation 1100 in accordance with Practice E527.

Note 1—See Specification B483/B483M for aluminum-alloy drawn tubes for general purpose applications; Specification B234 for aluminum-alloy drawn seamless tubes for condensers and heat exchangers; and Specification B241/B241M for aluminum-alloy seamless pipe and seamless extruded tube.

Note 2—Throughout this specification, use of the term alloy in the general sense includes aluminum as well as aluminum alloy.

1.3 A complete metric companion to Specification B210 has been developedSpecification B210M; therefore, no metric equivalents are presented in this specification.

1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.

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.

TABLE 1 Chemical Composition Limits^{A, B, C, D}

^A Limits are in weight percent maximum unless shown as a range or otherwise stated.

^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 obtained 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-off method of Practice E29.

^D In case of 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.

^E 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.

^F Other elementsTotal shall be the sum of unspecified metallic elements 0.010 % or more, rounded to the second decimal before determining the sum.

^G Vanadium 0.05 % max.

^H 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.

^I Alloy clad with Alloy 7072.

^J Composition of cladding alloy as applied during the course of manufacture. The samples from finished tube shall not be required to conform to these limits.

^K A Zr +Ti limit of 0.25 percent maximum may be used with this alloy designation for extruded and forged products only, but only when the supplier or producer and the purchaser have mutually so agreed. Agreement may be indicated, for example, by reference to a standard, by letter, by order note, or other means which allow the Zr +Ti limit.
