Abstract: A steel cord that is suitable for reinforcing rubber articles such as tires. The inventive steel cord enables to completely eliminate the presence of cobalt in a tire when combined with the proper cobalt free compound. Advantageously the steel cord adheres equally well to rubbers containing organic cobalt salts. The inventive wire is different from prior art steel cords in that the brass coating now comprises iron particles. The iron particles have a size between 10 nm and 10 000 nm. The presence of iron mitigates the adhesion retention loss of the rubber to steel cord bond in a hot and humid environment. It is a further advantage that the inventive steel cord does not contain any intentionally added cobalt thereby contributing to the elimination of harmful substances in the production area as well as the environment.

Abstract: A copper alloy coated bead wire is coated with a resin coating comprising corrosion inhibiting reagent to promote corrosion resistance and bead/rubber adhesion retention. The thin and continuous resin coating comprising corrosion inhibiting reagent is formed by applying a solvent containing both corrosion inhibiting reagent and resin on the copper alloy coated the bead wire. The thin and continuous resin coating comprising corrosion inhibiting reagent achieves synergetic effect. On one hand, the thin resin coating comprising corrosion inhibiting reagent allows a sulfur/copper bond to be formed between bead wire and the adjacent rubber. On the other hand, the continuous resin coating comprising corrosion inhibiting reagent facilitates corrosion resistance.
