The present invention relates to an electrical conductor made of copper alloy consisting essentially of, as percentage by weight relative to the total weight of the alloy : chromium : 0.15-1.3%, zirconium : 0.01-0.15%, silver : 0.01-0.15%, rare earth elements, in particular cerium, yttrium or a mixture thereof : 0.001-0.1%, copper : the remainder, and the inevitable impurities and having a conductivity greater than or equal to 85% IACS, advantageously greater than 89% IACS. It also relates to a process for manufacturing same and to the use thereof as a conducting core of cables or as a cable-shielding braid.
