PURPOSE:To obtain an Ag alloy filler metal for brazing suppressing the surface roughening of the filler metal after brazing and also suppressing the occurrence of ruggedness, by incorporating a specified amt. of a specified component into an Ag-Cu-In alloy. CONSTITUTION:This Ag alloy filler metal for brazing is an alloy consisting of 20-55wt.% Cu, 3-15wt.% In, 0.001-1.0wt.% at least one among Ti, Zr, V and Nb and the balance Ag. Since the surface roughening of the filler metal after brazing is suppressed and the occurrence of ruggedness is also suppressed, even when a member brazed with the filler metal is subjected to acid cleaning or plating, only a small amt. of a cleaning soln. or the like enters the surface recesses in the filler metal and the tarnish and corrosion of the brazed part are inhibited.
