1、Designation: B 566 04aStandard Specification forCopper-Clad Aluminum Wire1This standard is issued under the fixed designation B 566; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses
2、 indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers bare round copper-clad alumi-num wire for electr
3、ical applications.1.2 Four classes of copper-clad aluminum wire are coveredas follows:Class 10ANominal 10 volume % copper, annealed.Class 15ANominal 15 volume % copper, annealed.Class 10HNominal 10 volume % copper, hard-drawn.Class 15HNominal 15 volume % copper, hard-drawn.1.3 The values stated in i

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 lota lot is any amount of wire of one class and sizepresented for acceptance at one time; such amount, however,not to exceed 100 production units.3.1.2 samplea quantity of p
7、roduction units (coils, reels,and so forth) selected at random from the lot for the purpose ofdetermining conformance of the lot to the requirements of thisspecification.3.1.3 specimena length of wire removed for test purposesfrom any individual production unit of the sample.4. Ordering Information4
8、.1 Orders for material under this specification shall includethe following information:4.1.1 Quantity of each size and class;4.1.2 Wire size, diameter in inches (see Section 7 and Table1);4.1.3 Class of wire (see 1.2 and Table 1);4.1.4 Packaging and shipping (Section 14 and packaginginspection if re

Materials and Manufacture5.1 The wire shall consist of a core of aluminum with acontinuous outer cladding of copper thoroughly bonded to thecore throughout and shall be of such quality as to meet therequirements of this specification.6. Gener
10、al Requirements6.1 Tensile Strength and ElongationThe copper-clad alu-minum wire shall conform to the tensile strength and elonga-tion requirements of Table 1. For intermediate diameters notlisted in Table 1, the elongation requirements of the nextsmaller size shall apply; in the case of tensile str
11、ength therequirements of the next larger size shall apply.6.2 ResistivityThe electrical resistivity at a temperature of20C shall not exceed the values prescribed in Table 2. SeeNote 1 for calculating electrical resistance.NOTE 1Relationships which may be useful in connection with thevalues of electr
12、ical resistivity prescribed in this specification are shown inTable 3. Resistivity units are based on the International Annealed CopperStandard (IACS) adopted by IEC in 1913, which is158 Vmm2/m and thevalue of 0.15328 Vg/m2at 20C are, respectively, the internationalequivalent of volume and weight re
13、sistivity of annealed copper equal to100 % conductivity. The later term means that a copper wire1minlengthand weighing 1 g would have a resistance of 0.15328 V. This is equivalentto a resistivity value of 875.20 Vlb/mile2, which signifies the resistance1This specification is under the jurisdiction o

18、onversion from one set of resistivity units to another.6.3 CohesionThe copper-clad aluminum wire, whentested in accordance with 10.4, shall be free from seams orsplits. Examination of the wire shall be made at a magnificationnot to exceed 103.6.4 AdhesionThe copper-clad aluminum wire, whentested in
19、accordance with 10.5, shall be free from claddingdelamination. Examination of the wire shall be made at amagnification not to exceed 103.6.5 JointsThe finished wire shall contain no joints orsplices.6.6 Copper ThicknessThe minimum copper thickness,when tested in accordance with 10.6, shall be not le
20、ss than thefollowing:6.6.1 Class 10A and 10H wire shall have a minimumthickness of not less than 3.5 % of the wire radius.6.6.2 Class 15A and 15H wire shall have a minimumthickness of not less than 5.0 % of the wire radius.6.7 Copper Volume (Area)The copper volume (area) perclass, when tested in acc
21、ordance with 10.6, shall meet thefollowing tolerances:6.7.1 Class 10A and 10H wire shall contain not less than8 % and not more than 12 % copper by volume (area).6.7.2 Class 15A and 15H wire shall contain not less than13 % and not more than 17 % copper by volume (area).7. Dimensions, Mass and Permiss
22、ible Variations7.1 The wire size shall be expressed as the diameter of thewire in decimal fractions of an inch to the nearest 0.0001 in.(0.003 mm) (Note 2). For diameters under 0.0100 in. (0.254mm), the wire shall not vary from the specified diameter bymore than 60.0001 in. (60.003 mm) and for diame
23、ters of0.0100 in. (0.254 mm) and over, the wire shall not vary fromthe specified diameter by more than 61 %, expressed to thenearest 0.0001 in. (0.003 mm).NOTE 2The values of the wire diameters in Table 1 are given to thenearest 0.0001 in. (0.003 mm) and correspond to the standard sizes givenin Spec
24、ification B 258. The use of gage numbers to specify wire sizes isnot recognized in this specification because of the possibility of confusion.A discussion of wire gages and related subjects is contained in “CopperWire Tables,” NBS Handbook 100.8.
