Abstract: An alloy material includes: a composition, in a composition range of a ternary alloy of silver (Ag), palladium (Pd), and copper (Cu), the composition containing 20 to 30 wt % of Ag, 35 to 55 wt % of Pd, and 20 to 40 wt % of Cu. The composition as a base is added with tin (Sn) in a range of 0.5 to 2.5 wt %, further added with any one of or a combination of cobalt (Co), chromium (Cr), and zinc (Zn) in a range of 0.1 to 1.0 wt %, and added with 0.01 to 0.1 wt % of either one of or a combination of iridium (Ir) and ruthenium (Ru).
