Standard Specification for 8000 Series Aluminum Alloy Wire for Electrical Purposes<char: emdash>Annealed and Intermediate Tempers
ABSTRACT
This specification covers 800 series aluminum alloys fabricated into round wires in annealed or intermediate tempers suitable for stranding into conductors or for solid single conductors, usually to be insulated. The wire shall be made from drawing stock meeting the chemical composition limits for aluminum, silicon, iron, copper, magnesium, zinc, and boron. The wire shall be free of imperfections and shall conform to specified values for tensile strength, elongation, and electrical resistivity. The specified values for the density of aluminum alloys and wire diameter, shall be taken for the calculation of mass and cross sections. Joints may be made in drawing stock and in the wire prior to final drawing, or during final drawing or in the finished wire by electrical-butt welding, cold-pressure welding, or by electric-butt, cold-upset welding. Details for each kind of test and measurement method (tensile strength test, resistivity measurement, diameter measurement, surface-finish inspection) are discussed thoroughly.
SCOPE
1.1 This specification covers 8000 series aluminum alloys fabricated into round wires in annealed or intermediate tempers suitable for stranding into conductors or for solid single conductors, usually to be insulated.
1.2 The SI values for resistivity are regarded as standard. For all other properties, the inch-pound units are regarded as standard and the SI units may be approximate.
Note 1—Aluminum alloys capable of meeting the requirements of this specification are listed in Table 1.
Note 2—The alloy and temper designations conform to ANSI H35.1. Unified Numbering System alloy designations are listed in Table 1 in accordance with Practice E527.
Note 3—Certain aluminum alloys may be subject to patent rights. U.S. patents numbers are shown in Table 1.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
