Standard Specification for Aluminum and Aluminum-Alloy Rivet and Cold-Heading Wire and Rods
This specification covers wire and rod in the alloys and the tempers suitable for manufacturing rivets and other similar items by cold-heading operations. The products covered by this specification shall be produced by extruding, rolling, or drawing, or a combination thereof, at the option of the producer. For heat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy, temper, and nominal diameter traceable to a heat-treat lot or lots, and subjected to inspection at one time. On the other hand, an inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy, temper, and nominal diameter subjected to inspection for non heat-treated tempers. Samples for chemical analysis shall be taken from the material by drilling, sawing, milling, turning, or clipping a representative piece or pieces to obtain a prepared sample. One tension test per specimen shall be taken. Resistance to stress corrosion cracking for each lot of specimen shall be established by testing the previously selected tension-test samples for lot acceptance purposes. Variations from the specified diameter, length, and straightness shall not exceed the permissible variations prescribed. The material shall be supplied in the mill finish and shall conform by the requirements of this specification and shall be commercially sound.
1.1 This specification covers wire and rod in the alloys (Note 1) shown in Table 1 and the tempers shown in Table 2 [Table 3] and Table 4 [Table 5], suitable for manufacturing rivets and other similar items by cold-heading operations.
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 wire and rod, see Specification B211, and for extruded wire and rod, see Specification B221.
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 The values stated in either SI units 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.
1.4.1 The SI units are shown either in brackets or in separate tables.
