NbTi Superconducting Wires

Supercon's standard product selection includes monofilament and multifilament NbTi superconducting wires with a wide range of filament count, filament size and copper-to-superconductor ratio. See the data table below for more details on your specific requirements.

Standard NbTi Supercon Conductors

Type	# Filaments	Cu:Sc	Applications / General Description
Multifilament Conductors
56S53	56	0.9:1	Multifilament superconductor for general purpose DC magnets. Commonly used for construction of NMR analytical systems.
54S43	54	1.3:1
54S33	54	2:1
42S25	42	3:1
30S18	30	4.5:1
MR24	24	7:1	Designed for use in NMR and MRI imaging magnets requiring more stability.
MR16	16	11:1
Monofilament Conductors
T48B-M	1.5:1	1	Single filament NbTi alloy clad with high conductivity cryogenic grade copper. Current density is well balanced with the size of the NbTi alloy core and the stabilization provided by the copper cladding. Applications include shim coils and liquid Helium level sensors.
T48B-G	3:1	1
