Copper Alloys

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.

Alloyed Conductor-Grade Coppers, Wrought

Alloyed Coppers are hardened with small quantities of Cr, Zr, Be, Ni, with the aim of increasing strength without greatly reducing electrical conductivity.
