ASTM B221 – 12 Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
ASTM B221
Abstract ASTM b221 pdf
This specification covers extruded bars, rods, wires, profiles, and tubes made from aluminum and aluminum alloys. All the products should be produced by hot extrusion or similar methods. The chemical composition of each material is determined in accordance with the specified suitable chemical and spectrochemical test methods. Samples for chemical analysis should be taken when the ingots are poured or from the finished or semi-finished products by drilling, sawing, milling, turning, or clipping. Tensile properties, elongation, and yield strengths of each product should conform to the requirements listed herein. Elongation requirements are not applicable for materials with sizes smaller than the specified limits.

 

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 extruded bars, rods, wire, profiles, and tubes in the aluminum alloys (Note 1) and tempers shown in Table 2.

Note 1—Throughout this specification, the use of the term alloy in the general sense includes aluminum as well as aluminum alloy.

Note 2—For rolled or cold-finished bar and rod refer to Specification B211, for drawn seamless tube used in pressure applications, Specification B210, for structural pipe and tube, Specification B429/B429M, and for seamless pipe and tube used in pressure applications, Specification B241/B241M.

Note 3—Structural pipe and tube produced in accordance with B221 is not intended for fluid-carrying applications involving pressure. Refer to either Specification B210 or B241/B241M, as appropriate, for seamless pipe and tube used in fluid-carrying applications involving pressure.

1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. 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.

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

1.4 A complete metric companion to B221 has been developedB221M; therefore, no metric equivalents are presented in this specification.

TABLE 1 Chemical Composition Limits A,B,C

Note—In case of a discrepancy between the values listed in Table 2 and 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” should be considered the controlling composition. The “Teal Sheets” are available at http://www.aluminum.org/tealsheets.

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 the purpose 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 the figures used in expressing the specified limit, in accordance with the rounding-off 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.

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

F 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.

G Be 0.0003 max for welding electrode, welding rod, and filler wire.

H Upon agreement between the purchaser and the producer or supplier, a Zr + Ti limit of 0.20 % max is permitted. Properties in Specification (Table 2) are not based on the Zirconium and Titanium algorithm.

I Zirconium, 0.10–0.25 %. The total for other elements does not include zirconium.

J Manganese plus chromium shall total 0.12–0.50.

K Lead 0.05 % max, Tin 0.9-1.5 %.

L Bismuth 0.30-0.9 %, Tin 0.35-1.2 %.

M Bismuth 0.20-0.8 % Lead 0.15-0.40 %.

N In 1965 the requirements for 6062 were combined with those for 6061 by revising the minimum chromium from “0.15 %” to“ 0.04 %.” This action cancelled alloy 6062.

O Bismuth 0.50-0.7 %, Lead 0.20-0.40 %,

P Bismuth and lead shall be 0.40–0.7 % each.

Q Zirconium 0.08–0.20 %. The total for other elements does not include zirconium.

R Composition of cladding alloy applied during the course of manufacture. Samples from finished tube shall not be required to conform to these limits.

S Upon agreement between the purchaser and the producer or supplier, a Zr + Ti limit of 0.25 % max is permitted. Properties in Specification (Table 2) are not based on the Zirconium and Titanium algorithm.

T Gallium 0.03 % max.
