Summary

The copper-silicon alloy shows appropriate mechanical and electrical properties, and is economically more favourable than the copper-nickel alloy matrix used currently. Moreover, the addition of silicon to copper prevents the formation of intermetallic compounds around the filaments. After extensive investigations on copper-silicon alloy as a matrix material, an ultrafine multifilamentary niobium-titanium/copper-2.5 wt% silicon composite wire has been successfully fabricated. The direct-current superconducting properties of the wire were adequate for use in electrical apparatus. A preliminary study has revealed that the alternating-current loss of the new wire is equivalent to that of a typical ultrafine multifilamentary niobium-titanium/copper-nickel composite wire.
