Cu-Ag Cu-Ag Cu-Ag ALLOY WIRE AND METHOD FOR PRODUCING Cu-Ag ALLOY WIRE

摘要

A high conductivity, and provides a method for producing high-strength Cu-Ag alloy wire and a Cu-Ag alloy wire. A Cu-Ag alloy wire made of a copper alloy containing Ag, Ag containing 0.1% by weight to 15% by weight, and consists of the balance of Cu and impurities. The Cu-Ag when chwihaeteul any observation field of view within the 1000nm × 1000nm in the alloy of the line cross-section, of which observation information precipitate of Ag present in the field of view, sub-precipitate with a maximum length of the area ratio of 100nm or less defined precipitate of the straight line to cut this is more than 40%. By the Ag in the presence of very fine particulate dispersed uniformly small, it is possible to enhance dispersion, as well as to further improve the strength, can have a high electric conductivity.
