Abstract

PURPOSE: The outside of high-concentration Cu-Sn alloy base enclosing Nb core material is covered with good-workable, low-concentration Cu-Sn alloy and its diameter is contracted, whereby annealing cycle is reduced, Nb3Sn formation efficiency is enhanced, and Sn plating thickness is decreased.
CONSTITUTION: One or more of Nb core materials 7 made of pure Nb rod, wire or powder are located in proper locations in a base 6 of rod, or pipe made of high- concentration Cu-Sn alloy containing 10 wt% or more of Sn. The product is covered by low-concentration Cu-Sn alloy pipe 8 whose Sn content is less than the base, for example less than 10 wt% of Sn. The so formed product undergoes diameter contraction such as extrusion and swaging, etc., and coated with Sn-plated layer 9 of desired thickness by electroplating or some other means. Next, the product experiences with heat diffusion treatment under vacuum or non-oxidizing atmosphere such as innert gas to produce Nb3Sn.
