Supercon's Standard Superconductors
|NbTi Superconducting Wires|
Supercon's standard product selection includes monofilament and multifilament NbTi (Niobium Titanium) superconducting wires with a wide range of filament count, filament size and copper-to-superconductor ratio.
The multifilament superconductors are designed for the construction of NMR analytical systems, NMR and MRI imaging magnets requiring more stability, and other general purpose DC magnets.
The monofilament NbTi alloys are clad with high conductivity cryogenic grade copper. The 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.
|Nb3Sn Superconducting Wires|
For high field (HF) applications, Supercon produces Nb3Sn (Niobium Tin) conductors manufactured by the bronze process. The bronze process offers superior manufacturability, allowing delivery of long length wire with high current density and low AC loss. A simplified reaction heat treatment for bronze Nb3Sn improves the reliability and manufacturability for the magnet producer.
|CuNi Resistive Wires|
|Designed for use in superconducting switches, particularly for use in coils designed to operate in the persistant mode. Highly resistive CuNi (90/10) matrix conductors.|
|Fine SC Wires|
|For your low-current applications that require diameters smaller than 0.3mm, Supercon carries several types of fine superconducting wires.|
|Supercon's experience and technical innovation enables us to customize conductors to your requirements. Whatever your filament count, size, shape, or cable configuration needs, we can work with you to develop and manufacture a suitable superconducting wire. Two recent examples of custom superconductors Supercon developed are the Very Small Filament (VSF) and the High Field (HF) NbTi supeconductor.|
|All standard electrical insulations can be applied - the most common being Formvar.|
|Size and Shape||Supercon composites can be made with a variety of uniform cross sections.|
|Critical Current and Field Requirements||Supercon NbTi superconductors can be used economically for fields up to 90 kilogauss. Short sample currents are guaranteed.|
|Stability Requirements||Specified in part by the copper to superconductor ratio (Cu:SC), this ratio may range as high as 10 to 1, or higher in soldered conductors.|
|Number and Size of Filaments||The number and size of superconducting filaments are determined by the current capacity and the stability requirements of the conductor. The superconducting filaments are twisted within the matrix to reduce magentization losses.|
|Matrix Material||High conductivity copper, because of its resistivity ratio and high thermal conductivity, is the most common matrix material. Other materials (e.g. CuNi or CuMn) can be used in special applications.|
|Insulation||All standard electrical insulations can be applied - the most common being Formvar.|
|Availability||Standard conductors available from stock. Custom conductor designs can be supplied with minimal lead times.|
