Abstract
A metal wire, having a steel core and being provided with a layer of cladding of a zinc/manganese alloy containing between 5% and 80% of manganese. The wire is used as a reinforcement structure for tires or other products of elastomer material. Several embodiments of a process for applying the cladding on the steel core by electrodeposition of the zinc/manganese alloy are also described.
