Copper alloys for electrical conductors are well documented and have widely accepted designations. The newer composites are not yet sufficiently well established to have internationally or nationally accepted codes or designations.
Conductor Grades of Copper, Wrought
Unalloyed coppers are used for electrical conductors where exceptional strength or high-temperature capability are not required.
