    Abstract

    This specification covers hard-drawn round copper alloy wires for electric conductors. The wires shall be made in any one of ten distinct alloys designated 8.5, 13, 15, 20, 30, 40, 55, 74, 80, and 85 in accordance with their increasing electrical conductivities. Specimens shall undergo tests to which they shall meet the required values for chemical composition, electrical resistivity, and mechanical and physical properties. The mechanical properties to be examined are elongation and tensile strength, while the physical properties in consideration are wire diameter, area, and density. The completed wire, to which no joints are to be made, shall be free from all imperfections not consistent with the best commercial practice.

    1.1 This specification covers hard-drawn round copper alloy wires for electric conductors.

    1.2 The copper alloy wires shall be made in any one of ten distinct alloys designated 8.5 to 85 in accordance with their increasing conductivities or designated by assigned UNS numbers (see Explanatory Note 1) as follows:

    Copper Alloy UNS
    No.
    Copper Alloy UNS
    No.
    Alloy 8.5C65100Alloy 40
    Alloy 13C51000Alloy 55C16500
    Alloy 15Alloy 74C19600
    Alloy 20Alloy 80C16200
    Alloy 30C50700Alloy 85C16200

    1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.3.1 ExceptionThe SI values of density and resistivity are to be regarded as standard.
