FILO METALLICO CON DOPPIO STRATO DI RIVESTIMENTO PER IL RINFORZO DI ARTICOLI IN MATERIALI ELASTROMERICI E ARTICOLI IN MATERIALI ELASTOMERICI RINFORZATI CON DETTO FILO

摘要

The invention relates to a metal wire for reinforcing articles made of elastomeric material, especially vehicle tyres. The wire in question has a coating formed by two concentric layers of zinc-nickel or zinc-cobalt alloys, the radially more internal layer of which has a zinc content greater than 90% whilst the radially more external layer has a nickel or cobalt content greater than 50%.
