<P>PROBLEM TO BE SOLVED: To provide a Cu-Ag alloy wire having high electrical conductivity and high strength, and to provide a method for producing the Cu-Ag alloy wire. <P>SOLUTION: The Cu-Ag alloy wire comprises a copper alloy containing Ag, wherein the Ag of 0.1 to 15 mass% is contained and the remainder comprises Cu and impurities. When an arbitrary observation viewing field is taken within 1,000 nm×1,000 nm in the cross section of this Cu-Ag alloy wire, the area ratio of crystalline precipitate, in which a maximum length of a straight line that cuts the crystalline precipitate does not exceed 100 nm, is at least 40%, in the crystalline precipitate of Ag existing in the observation viewing field. By uniformly dispersing extremely fine particulate Ag in the alloy, it is possible to improve dispersion strengthening, thereby improving strength more, while also giving the alloy wire high electrical conductivity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
