1.1 This specification covers 6101 aluminum-alloy extruded bar, rod, tube, pipe (Schedules 40 and 80), and structural profiles (channels and angles) in selected tempers for use as electric conductors as follows:

1.1.1 Type B Hot-finished bar, rod, tube, pipe and structural 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 E 527 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 equivalanets; therefore each sytem shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
