Abstract
A method of making wire rope which when finished comprises a plural number of wires assembled in a twisted state. Each of said wires is first electroplated with zinc and thence diametrically adjusted as to its length by the application of a cold working thereto. Then the wire rope is further electroplated with tin thereby obtaining corrosion-proof and solderable property besides becoming resistant against friction and the like due to its surface lubrication in comparison with conventional wire ropes.
Claims1

- b. extending the strands by cold working to a predetermined diameter;
- c. twisting the strands into a wire rope;
- and,
- d. electroplating a tin film over the finished rope covering the outer surface of the rope.
