Standard Specification for Hard-Drawn Copper Alloy Wires for Electric Conductors
The following bibliographic material is provided to assist you with your purchasing decision:
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 Note 1) as follows:
| Copper Alloy UNS No. | Copper Alloy UNS No. | ||
| Alloy 8.5 | C65100 | Alloy 40 | |
| Alloy 13 | C51000 | Alloy 55 | C16500 |
| Alloy 15 | Alloy 74 | C19600 | |
| Alloy 20 | Alloy 80 | C16200 | |
| Alloy 30 | C50700 | Alloy 85 | C16200 |
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 Exception—The SI values of density and resistivity are to be regarded as standard.
