摘要： A method for manufacturing a Sn-based alloy containing a finely dispersed Sn—Ti compound includes melting Sn by heating to a temperature in a range from 1300 to 1500° C. in vacuum or an inert gas atmosphere, adding 0.1 to 5% by weight of Ti followed by melting by heating, and casting the molten alloy into a copper mold directly or through a pouring cup. The Sn-based alloy obtained by this method contains the Sn—Ti compound having a maximum particle diameter of 30 &mgr;m and a mean particle diameter of 5 to 20 &mgr;m. A precursor of a Nb3Sn wire is also obtained by an inner diffusion method using this Sn-based alloy. The Nb3Sn wire manufactured by using the Sn-based alloy of the present invention exhibits excellent superconductive characteristics. The method of the present invention enables the ingot to be free from a shrinkage cavity appearing during prior art manufacturing processes.
