Abstract

PURPOSE:To lower a liquid phase temp. and to enable brazing at a low temp. by specifying the contents of Ag, Cu, Zn, Ga, and Sn in a gold alloy filler metal. CONSTITUTION:The component compsn. of the gold alloy filler metal is specified, by weight %, to 60-75% Au, 5-15% Ag, 5-15% Cu, 3-10% Zn, 0.5-10% Ga, and 0.5-10% Sn. The reason for limiting the component compsn. is to confine Au to a 60-75wt.% range in order to obtain K15-K18 gold alloy filler metal. Ag contributes to an improvement in flowability and brazing strength. There is no effect at <5wt.% and the increase of the m.p. is high when the content exceeds 15wt.%. Cu improves brazing strength. There is no effect at <5wt.% and the increase in the m.p. is high when the content exceeds 15wt.%. Zn lowers the m.p. and improves the flowability thereof. The effect of lowering the m.p. is low at <3wt.% and the brazing strength is degraded if the content exceeds 10wt.%. Ga; Sn lower the m.p. and improve the flowability thereof. 0.5-10% In is incorporated into this gold alloy filler metal at need.
