(Specification)Standard Specification for Aluminum-Alloy Extruded Bar, Rod, Tube, Pipe, Structural Profiles, and Profiles for Electrical Purposes (Bus Conductor)
Standard Specification for Aluminum-Alloy Extruded Bar, Rod, Tube, Pipe, Structural Profiles, and Profiles for Electrical Purposes (Bus Conductor)
ABSTRACT
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. The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. Pipe or tube may be produced through porthole or bridge type dies. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively. Electrical resistivity and conductivity shall be determined.
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.
1.4 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.

6.2 Lot Definition—An inspection lot shall be defined as follows:

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
producer by analyzing samples taken at the time ingots are poured, or samples taken from the finished or semifinished product.
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—The number of samples taken for determination of chemical composition shall be as follows:
7.2.1 When samples are taken at the time the ingots are poured, at least one sample shall be taken for each group of ingots
poured simultaneously from the same source of molten metal.
7.2.2 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 that not more than one sample shall be required per piece.
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.
7.4 Methods of Analysis—The determination of chemical composition shall be made in accordance with suitable chemical (Test
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 upon between the producer and purchaser.

To determine conformance to this specification, each value shall be rounded off to the nearest 0.1 ksi (1 MPa) for strength in accordance with the rounding-off method
of Practice E29.

8. Heat Treatment
8.1 Except as noted in 8.2, heat treatment shall be in accordance with Practice B918.
8.2 Unless otherwise specified, Alloy 6101 may be solution heat-treated and quenched at the extrusion press in accordance with
Practice B807/B807M in the production of T6-type tempers.
9. Tensile Properties of Material as Supplied
9.1 Limits—The material shall conform to the tensile properties in Table 2.
9.2 Number of Specimens:
9.2.1 For material having a nominal weight of less than 1 lb/linear ft [up through 1.7 kg/linear m], one tension test specimen
shall be taken for each 1000 lb [500 kg], or fraction thereof, in the lot.
