Abstract
A wire rope is formed by twisting two different metal wires which vary from each other by at least 5% in their acoustic wave propagation velocities. In the longitudinal direction, the two different metal wires are combined in two embodiments: first wires of steel material and wires of stainless steel material, or secondly, wires of a steel material and wires of a beryllium 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.
