Ｃｕ-Ｓｎ-Ｔｉ alloy for Ｎｂ３Ｓｎ superconducting wire
	■Property 　・The newly named “Mizuta Method”※consisting of gas shielding, direct cooling, directional solidifying and electromagnetic stirring realizes addition of titanium to copper-tin alloy under atmospheric conditions and supply of copper-tin alloy with less segregation of tin and titanium and with less micro-and macro-defects. 　・For Nb3Sn superconducting wire, Cu-13/16%Sn alloy with 0.3%Ti is usually supplied to the market. 　・Comparing with the vacuum melting process, productivity of the Mizuta Method is noticeable. 　Besides, the melting furnaces and heat-treatment furnaces are exclusive preventing contamination of other alloy elements. 　・Unit weight of Cu-Sn-Ti billet is 10〜300kgs in various diameters. 　※Patented with KOBE STEEL, LTD
