Abstract

1387621 Making cables IMPERIAL METAL INDUSTRIES (KYNOCK) Ltd 30 March 1972 [15 April 1971] 9495/71 Headings H1A and A4D A metal composite is made by assembling a plurality of longitudinally extending elements of a non-ferromagnetic metal having an electrical resistivity at 0‹C of less than 3 micro ohms cm., separating each element from the other elements by a layer of metal having a higher electrical resistivity than that of the first mentioned metal, screwing the assembly together, and longitudinally extending the assembly to elongate the elements to produce filaments and to metallurgically bond the components of the assembly together. In one embodiment, Fig. 4, rods 5 of hexagonal crosssection are produced by extruding at a temperature of 550‹C and then drawing an assembly comprising a high purity copper rod which has been inserted in a tube of a copper 30 wt. per cent nickel alloy. The rods 5 are then inserted in a can 6 of the above cupro-nickel alloy, with cupro-nickel covered copper cores 6a filling the extra spaces, and the assembly extruded at 950‹C and drawn. In the embodiment of Fig. 6 strips of Ti 6 wt. per cent Al 4 wt. per cent V alloy are inserted in longitudinal slots in the outer wall of a copper can and a can of the above titanium alloy slid over the copper can. The assembly is then extruded at temperatures from 450-580‹C and machined to produce a composite can as shown in Fig. 6, having an outer sheath 11 of the titanium alloy with segments 12 of the titanium alloy separating parts 13 of copper. The composite can is then filled with copper filaments 9 covered in the titanium alloy and then assembly extruded at a temperature of 500 Œ 75‹C. A composite tube, as shown in Fig. 8, having segments 20 of copper and shells 22 and 23 and barriers 21 of the cupronickel alloy, is formed in a similar manner to the formation of the composite can of Fig. 6 without the machining step. In the embodiment shown in Fig. 9 aluminium wires 25 covered with a copper 1 wt. per cent tin alloy and having a hexagonal cross-section are inserted between the copper-tin alloy tubes 27, 28 and the assembly extruded at 350-450‹C and drawn to give a hollow tube. Examples of other alloys used are described in the Specification.
