    摘要: Titanium having a thermal shrinkage factor close to that of Nb.sub.3 Sn superconducting wire, whereby it gives rise to little degradation of the properties of the superconducting wire and also offers a good balance between strength and toughness at liquid helium temperature, making it highly suitable as a conduit pipe material used as a seal for liquid helium for high-magnetic-field superconducting coil applications. The present invention focusses on the major effect on strength and toughness of titanium material that the oxygen content has, and appropriately controls the oxygen and other impurities content of pure titanium to provide titanium material comprising, in mass %, 0.07 to 0.13 percent O, up to 0.10 percent Fe, up to 0.10 percent C+N, and up to 0.005 percent H, with the remainder being Ti and unavoidable impurities, said titanium exhibiting mechanical properties and fracture toughness of base metal and welded portions which meet the requirements for use as titanium for conductor conduit in superconducting coil.
