Abstract:
A silver brazing material containing silver, copper, zinc, manganese, nickel, and tin as indispensable constituent elements. The silver brazing material includes 35 mass % or more and 45 mass % or less silver, 18 mass % or more and 28 mass % or less zinc, 2 mass % or more and 6 mass % or less manganese, 1.5 mass % or more and 6 mass % or less nickel, and 0.5 mass % or more and 5 mass % or less tin, with the balance being copper impurities. Within these compositional ranges, a predetermined relation is set between the manganese content and the nickel content, whereby the silver brazing material can be provided with excellent characteristics also in terms of processability or wettability. In the silver brazing material of the present invention, the silver content is reduced, and also melting point reduction and the narrowing of the temperature difference between solidus temperature and liquidus temperature are attempted.
