<P>PROBLEM TO BE SOLVED: To provide a hardly oxidizable fine wire of Cu-Mn based brazing filler metal which has satisfactory brazing property at ≤1,000°C, and also can be subjected to cold working, and to provide a method for producing the same. <P>SOLUTION: The Cu-Mn based brazing filler metal fine wire is composed of, by mass, 20 to 45% Mn, and the balance Cu with inevitable impurities, and in which a coating film having a composition satisfying the following inequality (1) is formed on the surface: Cu%/(Cu%+Mn%)≥0.85 (1). Further, in the method for producing the Cu-Mn based brazing filler metal fine wire, hot working and/or heat treatment at 600°C or above and at a solidus temperature or below, and the subsequent cold drawing are performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
