NbTi Wire-in-Channel for applications requiring a high copper-to-superconductor ratio (~5:1 or greater), OST has pioneered an economical fabrication technique used in the production of many thousands of tons of superconductor.
Standard Features
By soldering an insert of NbTi and copper into a copper channel of the desired dimensions, we both avoid processing large quantities of copper and allow standard core wire billet designs to be applied to a variety of final products. The technique naturally yields long continuous lengths, and is suitable for persistent magnets. Wire-in-channel is typically insulated by a polyester braid, which we apply in house. Other insulation schemes are also available.
