standard by ASTM International, 04/01/2020
Full Description
1.1This specification covers hard-drawn round copper alloy wires for electric conductors.
1.2The 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 | Copper Alloy UNS | ||
| 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 |
1.3The 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.
1.3.1Exception-The SI values of density and resistivity are to be regarded as standard.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
