PURPOSE:To provide a titled alloy braze material of a low cost by the specific composition contg. Ag, Si and at least one kind of Fe, Ni and Co, and consisting of the balance Cu. CONSTITUTION:This Cu-Ag type alloy braze material of a low content of Ag has the following composition by weight %: It has the composition contg. 5-35% Ag, 2.5-13% Si and 1-10% >= at least one kind of Fe, Ni and Co, and if necessary 1-10% >= Sn and/or In, and consisting of the balance Cu and unavoidable impurities. Although this alloy braze material is relatively low in the content of Ag, it has extremely low vapor pressure and m.p. and has good wettability. |
