Abstract
A precipitation-hardening alloy, including 17 to 23.6 at % of Ag, 0.5 to 1.1 at % of B, and a total of 74.9 to 81.5 at % of Pd and Cu, wherein the at % ratio of the Pd and Cu is 1:1 to 1:1.2, and the rest includes In and inevitable impurities. This provides an alloy with good overall balance, having all of maintaining low specific resistance, at least almost equal to that of conventional Ag—Pd—Cu alloys, and also having contact resistance stability (oxidation resistance), good plastic workability, and higher hardness than before.
