Process and Cost Optimization of Aluminum Stabilized NbTi Superconducting Wire

Objective

Develop a cost-effective manufacturing technology for aluminum stabilized NbTi superconducting wire.

Technical Approach

  • Investigate manufacturing process used for non-superconductor applications that may have potential for cladding high-purity aluminum onto a superconductive core wire
  • Expand technology of current cladding process to meet conductor requirements
  • Conduct manufacturing cost assessment for successful cladding technologies
  • Utilize process modeling to enhance and optimize the cladding technologies
  • Transfer cladding technologies to industry

Benefits

The improved manufacturing technology will result in significant cost savings of 30–40 percent over the presently used co-extrusion aluminum cladding process. Low-temperature aluminum stabilized superconducting wires meet performance requirements and offer a 40–50 percent weight reduction and ten times the thermal stability over equally sized, all-copper wire.

Implementation

An integrated project team consisting of various industrial partners, Naval Surface Warfare Center (NSWC) and the NCEMT was formed to address the manufacturing challenges. Information will be transferred to industry through a Web site, workshops and technical publications. The results of this project will enable magnet producers to competitively procure aluminum stabilized NbTi superconductor wire for mine sweeping and other applications.

Status
