PURPOSE:To obtain a titled material which is excellent in corrosion resistance at the time of use and in a post-treatment process, and also to hold it in sufficient spreading property and wettability by forming a solder material by adding Ge, Pd and Li of a specified quantity to Ag. CONSTITUTION:A silver solder material is constituted of 0.05-19% Ge, 0.01-10% Pd, 0.01-2% Li, and Ag as a balance. Also, by adding one kind or two kinds or more of Fe, Co and Ni to an Ag-Ge-Pd-Li compound alloy, in case when a base metal of Fe, Co and Ni, and their alloy, for instance, 42 Fe-Ni, covar, stainless steel, etc. has been soldered, the metallic organization is fined and also the soldering strength is improved. |
