Abstract

One aspect relates to a method for manufacturing a cable. The method for manufacturing the cable includes the steps of providing several raw wires made of a wire material, drawing the raw wires into wires, coiling the wires into a cable, and heat treating the cable. The wire material includes an alloy including the following alloy components:
a) Cr in the range from about 10 to about 30 wt. %; b) Ni in the range from about 20 to about 50 wt. %; c) Mo in the range from about 2 to about 20 wt. %; d) Co in the range from about 10 to about 50 wt. %.

The Al content of the Cr, Ni, Mo and Co alloy is less than about 0.01 wt. % and each wt. % is based on the total weight of the alloy.

First claim

What is claimed is:

1 . A method for manufacturing a cable, comprising:
providing several raw wires made of a wire material; drawing the raw wires into wires; coiling the wires into a cable; and heat treating the cable; wherein the wire material includes an alloy comprising the following alloy components: Cr in the range from about 10 to about 30 wt. %; Ni in the range from about 20 to about 50 wt. %; Mo in the range from about 2 to about 20 wt. %; Co in the range from about 10 to about 50 wt. %; wherein the Al content of the alloy is less than about 0.01 wt. %; and wherein each wt. % is based on the total weight of the alloy.

2 . The method of claim 1 , wherein the Cr, Ni, Mo and Co components are major constituents of the alloy with at least about 95 wt. % of the alloy being Cr, Ni, Mo and Co.

3 . The method of claim 1 , wherein the raw wires are drawn with a cold work percentage in a range of 98 and 99%.

4 . The method of claim 1 , wherein the raw wires are drawn with a cold work percentage in a range of 80 and 86%.

5 . The method of claim 1 , wherein the heat treatment of the cable is in a range of 480 to 750° C. with a dwell time of 5 to 6 seconds.

6 . The method of claim 1 , wherein the heat treatment of the cable is a stress relief treatment in a temperature range of 480 to 580° C. to improve a low cycle fatigue performance of the cable.

7 . The method of claim 1 , wherein the heat treatment of the cable is an annealing in a temperature range of 780 to 810° C. to improve a high cycle fatigue performance of the cable.

8 . The method of claim 1 , further comprising an initial drawing of a raw material into the raw wires.

9 . The method of claim 8 , wherein the raw material is drawn with a cold work percentage in a range of 95 and 96%.

10 . The method of claim 1 , further comprising an initial heat treatment of the raw wires before the drawing of the raw wires into the wires.

11 . The method of claim 10 , wherein the initial heat treatment of the raw wires is an annealing in a temperature range of 875 to 1100° C.

12 . The method of claim 1 , wherein the wire material further includes an additional material different to the Cr, Ni, Mo and Co alloy, and wherein the additional material forms a core and the Cr, Ni, Mo and Co alloy forms a shell around the core when the wire is seen in a cross section.

13 . The method of claim 1 , wherein the wire material further includes an additional material different to the Cr, Ni, Mo and Co alloy, and wherein the Cr, Ni, Mo and Co alloy forms a core and the additional material forms a shell around the core when the wire is seen in a cross section.

14 . A cable comprising drawn, coiled and heat treated wires made of a wire material,
wherein the wire material includes an alloy comprising the following alloy components:
a) Cr in the range from about 10 to about 30 wt. %;
b) Ni in the range from about 20 to about 50 wt. %;
c) Mo in the range from about 2 to about 20 wt. %;
d) Co in the range from about 10 to about 50 wt. %;
wherein the Al content of the alloy is less than about 0.01 wt. %; and wherein each wt. % is based on the total weight of the alloy.

15 . A medical device comprising a cable of claim 14 as a lead.
