The paper discusses the fabrication of Nb-Ti base superconducting wires having the superconductor packing factor of 15-20% and superconducting filaments 70-80 {mu}m dia. Three methods of precursor fabrication were tried. The NbTi-50 alloy base superconducting wire was fabricated to be used for the magnet system of a NMR-tomograph; the wire diameter is 0.85 mm; the packing factor is 16%; the maximum length of a single piece is 29 km{sub 2}. The critical current density is 6.1 {times} 10{sup 5} A/cm{sup 2} in the magnetic field of 1 T. The paper also presents the superconducting properties of similar wire on the NbTi-55 alloy base.
