FERMI HIGH PERFORMANCE AND QUALITY!
PRODUCTS CENTER
Nb₃Sn superconducting wire
Nb₃Sn material has the nature of higher the upper critical magnetic field ~22 T (Hc2) and critical temperature ~18 K (Tc) than NbTi, so it is widely used in high magnet field. Wecan supply the Nb3Sn wire in both Internal Tin process and Bronze process, with  low hysteresis loss and high critical current. The insulation material could be chosen between S-glass braid and Cr coating, if needed.
