A method applied today includes placement of niobium-titanium alloy-based blank in a copper or copper-based glass, sealing, hot extrusion and cold deformation to produce a rod, cutting of the said rod to parts, consequent assembly of separate rod parts in the copper or copper-based glass to obtain the required number of niobium-titanium fibers in the last composite blank, cold deformation, annealing and final deformation.

In the newly-developed method, rods placed in the last composite blank are preliminary subjected to cold deformation with intermediate annealing at the temperature of 385-420° C within 10 to 100 hours. After that, the last composite blank is subjected to cold deformation in a way that total deformation value would cover all available gaps (but not less than 10%). Additional annealing is conducted at certain temperature and time modes which correspond to intermediate annealing mode.
