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.

Scope

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 ) as follows:

Copper Alloy UNSNo.Copper Alloy UNSNo.
Alloy 8.5C65100Alloy 40
Alloy 13C51000Alloy 55C16500
Alloy 15Alloy 74C19600
Alloy 20Alloy 80C16200
Alloy 30C50700Alloy 85C16200

1.3 The SI values of density and resistivity are to be regarded as standard. For all other properties the inch-pound values are to regarded as standard, and the SI values may be approximate.
