A plurality of filaments are selected from a copper alloy filament including: a copper alloy filament including the A element; copper alloy filament including the B element; a copper alloy filament including both the elements the A and the B; a first metallic filament having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a second metallic filament coated with an oxide layer; a copper filament containing the A element and having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a copper filament containing the B element and having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a third metallic filament containing the A element and coated with an oxide layer; a fourth metallic filament containing the B element and coated with an oxide layer; the first to fourth metallic filaments being substantially free of any component which provides an adverse effect on the production of the superconductor. The selected filaments are arranged to form element filaments bundle so that the superconductor is produced in a subsequent heat treatment. The bundle is drawn and then heated under an oxidizing atmosphere for producing the superconductor.

摘要： A method of fabricating a superconductive electrical conductor of Nb.sub.3 Sn type comprises a step of covering an elongated core member made of Nb with a covering member made of a third element selected from the group consisting of Ti, Ta, In, Hf, Al and Si. The core member covered with the covering member is covered with a tubular matrix made of a Cu-Sn alloy or a combination of Cu with Sn to form a composite wire element. Such wire elements are assembled in a tubular matrix made of a Cu-Sn alloy, Cu or a combination of Cu with Sn and reduced in diameter to form a multi-core composite wire element having a desired diameter. The assembling and reducing processing is effected at least one to form a multi-core composite wire which is then subjected to a diffusion heat-treatment to form an intermetallic compound of Nb.sub.3 Sn and the third element in the peripheral portion of the core member.
