1. Scope*
1.1 This specification covers 6101 aluminum-alloy extruded bar, rod, tube, pipe, (Schedules 40 and 80), structural profiles, and
profiles in selected tempers for use as electric conductors as follows:
1.1.1 Type B—Hot-finished bar, rod, tube, pipe, structural profiles and profiles in T6, T61, T63, T64, T65, and H111 tempers with
Type B tolerances, as shown in the “List of ANSI Tables of Dimensional Tolerances.”
1.1.2 Type C—Hot-finished rectangular bar in T6, T61, T63, T64, T65, and H111 tempers with Type C tolerances as listed in the
tolerances and permissible variations tables.
1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy
designation in accordance with Practice E527 is A96101 for Alloy 6101.
NOTE 1—Type A material, last covered in the 1966 issue of this specification, is no longer available; therefore, requirements for cold-finished rectangular
bar have been deleted.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.3 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system
may not be exact equivalents; therefore each system shall be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
This specification is under the jurisdiction of ASTM Committee B07 on Light Metals and Alloys and is the direct responsibility of Subcommittee B07.03 on Aluminum
Alloy Wrought Products.

5. Manufacture
5.1 The bars, rods, tubes, pipes, structural profiles, and profiles shall be produced by hot extrusion or by similar methods at the
option of the producer, provided that the production method results in material that meets all requirements of this specification.
Pipe or tube may be produced through porthole or bridge type dies when specified by the purchaser.
6. Quality Assurance
6.1 Responsibility for Inspection and Tests—Unless otherwise specified in the contract or purchase order, the producer is
responsible for the performance of all inspection and test requirements specified herein. The producer may use his own or any other
suitable facilities for the performance of the inspection and test requirements specified herein, unless disapproved by the purchaser
in the order or at the time of contract signing. The purchaser shall have the right to perform any of the inspections and tests set
forth in this specification where such inspections are deemed necessary to assure that material conforms to prescribed requirements.
6.2 Lot Definition—An inspection lot shall be defined as follows:
6.2.1 For heat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy,
temper, and nominal dimensions traceable to a heat-treat lot or lots, and subjected to inspection at one time.
6.2.2 For nonheat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form,
alloy, temper, and nominal dimensions subjected to inspection at one time.
7. Chemical Composition
7.1 Limits—The material shall conform to the chemical composition limits in Table 1. Conformance shall be determined by the

If chemical composition has been determined during the course of manufacture, analysis of the finished product shall not be
required.
NOTE 2—It is standard practice in the United States aluminum industry to determine conformance to the chemical composition limits prior to further
processing of ingots into wrought products. Due to the continuous nature of the process, it is not practical to keep a specific ingot analysis identified with
a specific quantity of finished material.
7.2 Number of Samples—If it becomes necessary to analyze bar, rod, tube, pipe, (Schedules 40 and 80), structural profiles, or
profiles for conformance to chemical composition limits, the method used for determination of chemicals composition shall be by
agreement between the producer and purchaser. Analysis shall be performed in accordance with Practices E716, Test Methods
E1251 or E3061, or ECN EN 14242 (ICP Method). The number of samples taken for determination of chemical composition shall
be as follows:
7.2.1 Methods of Sampling—When samples are taken at the time the ingots are poured, at least one sample Samples for chemical
analysis shall be taken for each group ofin accordance with Practice B985ingots poured simultaneously from the same source of
molten metal.
7.2.2 Methods of Analysis—When samples are taken from the finished or semifinished product, a sample shall be taken to represent
each 4000 lb (1800 kg), or fraction thereof, in the lot, except thatAnalysis shall be performed in accordance with Test Method
E1251not more than, Test Method E3061one sample shall be required per piece., or CEN EN 14242 (ICP Method).
7.3 Methods of Sampling—Samples for determination of chemical composition shall be taken in accordance with one of the
following methods:
7.3.1 Samples for chemical analysis shall be taken from the material by sawing, milling, turning, or clipping a representative piece
or pieces to obtain a prepared sample of not less than 75 g. Sampling shall be in accordance with Practice E55.
7.3.2 Sampling for spectrochemical analysis shall be in accordance with Practices E716. Samples for other methods of analysis
shall be taken by methods suitable for the form of material being analyzed and the type of analytical method used.
7.3 Methods of Analysis—The determination of chemical composition shall be made in accordance with suitable chemical (Test
B317/B317M − 23
Methods E34) or spectrochemical (Test Methods E607 and E1251), methods. Other methods may be used only when no published
ASTM method is available. In case of dispute, the methods of analysis shall be agreed uponOther methods of analysis or in the
case of dispute may be by agreement between the producer and purchaser.
8. Heat Treatment
8.1 Except as noted in 8.2, heat treatment shall be in accordance with Practice B918B918/B918M.
8.2 Unless otherwise specified, Alloy 6101 may be solution heat-treated and quenched at the extrusion press in accordance with

be taken for each 1000ft1000 ft [300 m], or fraction thereof, in the lot.
9.2.3 Other procedures for selecting samples may be employed if agreed upon between the producer and the supplier or purchaser.
9.3 The geometry of test specimens and the location in the product from which they are taken shall conform to Test Methods B557.
[B557M].
9.4 Test Methods—The tensile testing shall be in accordance with Test MethodMethods B557. [B557M].
9.5 Retests—When there is evidence that the test specimen is defective or is not representative of the lot of material, retesting shall
be performed in accordance with Sections 8 and 9 of Test MethodMethods B557. [B557M].
