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 8.5 | 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 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.
