Niobium tubes, niobium rod and NbTi alloy are applied in superconductor application. Nb tubes of OD 21mm is for MgB2 superconducting wire application.
Mixed powers Mg+Br are put inside the niobium tubes. The Nb tubes are covered by the multiple tubes like Cu & Monel. And the outer Cu & Monel tube play a stabilizer role. After that they should be extruded three or four times. Combined with Cu & Monel tube, Nb tubes and Mg+Br powers, they are finally drawn into diameter 1.0mm MgB2 superconducting wire without disconnection. NbTi alloy of OD 62mm & Nb tube of OD63.5mm & OD38.5mm is for NbTi superconducting wire application. Nb rod is for Nb3Sn superconducting wire application.
Niobium titanium superconducting material can be made into a variety of compound practical materials by conventional deformation and heat treatment process.
Used in a 2-8t medium and low magnetic field, the amount of raw materials and manufacturing costs are much lower than other superconductors and other manufacturing technologies. Niobium titanium superconductor is extensively used in magnetic resonance imaging (MRI) magnets for modern medical diagnosis. The annual consumption of NbTi superconductivity has reached 1000 tons.
