Properties（Theoretical）
Niobium titanium alloy is an important alloyed superconductor material. Its superconductive transition temperature is 8K to 10K. If other elements are added into the alloy, superconductivity will be improved.
Niobium titanium alloy is sintered from alloyed powder. We use vacuum electrode arc furnace or electron-beam furnace to melt the alloyed ingots. The niobium titanium alloys can be in various forms such as sheet, bar, wire, or target.
Properties of superconducting material
1.Zero resistive
2.Complete diamagnetism Superconductivity is used in magnetic resonance imaging and magnetic resonance machines for medical and scientific instruments.
3.Josephson effect
4.Isotopic effect
Niobium titanium alloy superconductor is the leading material in superconducting industry. Together with Nb3Sn superconductor, it the first choice for practical superconducting magnet applications. It has high upper critical magnetic field (about 11T at 4.2K and 14T at 2K). In addition, it can be drawn well with copper. NbTi has good process plasticity, very high strength and good superconducting properties. The raw material of niobium titanium alloy superconductor and manufacturing costs are much lower than other superconducting materials. NbTi alloy can be heat treated to improve its superconducting properties before being assembled for twisting, winding and other applications. These advantages including its yield strength that is close to the steel will keep the NbTi superconducting alloys widely used for a quite long time.
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
