them with regard to the metal wires of interest here of course various steel wires are to be considered but in particular also wires of nickel or of an austenitic nickel chrome alloy have proven their worth austenitic nickel chrome alloys were processed in the form of wires with a diameter of below 0 5 mm into doubled yarns and these processed further into a cable with a diameter of 12 to 13 mm such a cable with a length of 600 mm permits the transmission of a maximal force of 57 8 kn the work to break here was also 10 u2032 000 nm what is essential according to the present invention is the fact that the cable must consist of three different constituent parts specifically on the one hand of yarns on the other hand of doubled yarns and thirdly of cords wherein simultaneously of each material constituent part this material should be present as yarn as well as doubled yarn and as cord only thus is it ensured that the three different extension regions of the same material may also be utilised it is only due to the combination of all three processing steps that the maximal extendibility of the material is also fully utilised although the processing of metal wires in the high security cable according to.
