<p>PROBLEM TO BE SOLVED: To provide an alloy brazing filler metal having a function capable of stabilizing the thickness of a brazing filler metal layer after joining without increasing working stages, thus, at the conventional cost. SOLUTION: In this alloy brazing filler metal, an alloy brazing filler metal essentially consisting of Sn and containing Ag of 0.05 to 3.5% by weight concentration is used as a base, Ge is contained by 0.1 to 5.0%, and also, Ge precipitated grains in which the maximum grain size lies in the range of 5 to 80μm are present.</p> |
