    Abstract: The invention is directed to several embodiments of metallic cord for the reinforcement of tires wherein one or more coaxial layers of metallic filaments are arranged around the metallic core filaments and twisted in the same direction at the same pitch. In one embodiment, the ratio of the diameter of the core filaments to the layer filaments is at least 1.28. In another embodiment, two of the core filaments have a first diameter and the third core filament has a second diameter smaller than the first diameter daimeter. In still another embodiment, two of the core filaments have a first diameter and a third of the core filaments has a second diameter smaller than the first diameter while the coaxial layer filaments have a third diameter equal to the second diameter. In another embodiment, the core has three core filaments twisted about each other and a coaxial layer of eight layer filaments arranged around the core filaments. In yet another embodiment, the core filaments have a first diameter and the layer filaments have a second diameter which is larger than the first diameter.

    Abstract: A wire rope is formed by twisting two different metal wires which vary from each other by at least 50% in their loss factors. The two different metal wires are combined in two embodiments: first, wires of steel material and wires of titanium containing material, or secondly, wires of a steel material and wires of chromium stainless steel material. In a preferred embodiment, a wire rope is formed by twisting a plurality of strands around a center core and two different metal wires as described above are employed to form the strands.
