Abstract

PURPOSE:To increase the resistivity of base materials, and to obtain a thermal type superconductive switch resisting excitation at high speed by adding one kind or more of elements in Sn, Ga, In, Zn, Tl, Bi to a CuNi base material and a base material for an NbTi superconductive wire by an NbTi group alloy filament. CONSTITUTION:5% Sn is added into a Cu-10% Ni alloy and molten, an NbTi bar is inserted into a Cu-Ni-Sn alloy tube, and the alloy tubes are bundled by two hundred and ninety five and machined to an outer diameter of 1mm., thus manufacturing an NbTi superconductive wire. The NbTi superconductive wire 1 is constituted by a CuNiSn base material 2 and NbTi filaments 3. The resistivity of the Cu-Ni-Sn base material 2 for the NbTi superconductive wire 1 manufactured in this manner is brought to a high value such as 20muOMEGA/cm, the NbTi superconductive wire 1 is wound and a thermal type superconductive switch is manufactured,and the resistance of the switch is brought to 105OMEGA and excitation at high speed is enabled.
