PURPOSE:To obtain an Au 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 Au-Ni alloy. CONSTITUTION:This Au alloy filler metal for brazing is an alloy consisting of 10-27wt.% Ni, 0.001-1.5wt.% at least one among B, Ga and Ge and the balance Au. 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.
