ABSTRACT:
This invention relates to metal wire used to produce reinforcing elements for articles of elastomeric material. The wire is provided with a coating ensuring at the same time a good resistance to corrosion, good values of initial adhesion, and a low decay, due to ageing, of the bond with the elastomeric material, said coating being constituted by two concentric layers of a Zn/Ni alloy, where the radially inner layer contains Zn in an amount ranging between 60% and 90% based on total layer and the radially outer layer contains Ni in an amount ranging between 60% and 80% based on the total layer.
