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 as follows:

Copper Alloy UNS Copper Alloy UNS No. 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 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.
