SN BASE BRAZING FILLER METAL OF LOW MELTING POINT

摘要

PURPOSE: To provide a brazing filler metal of low melting point where component elements are not evaporated and the excellent wettability is demonstrated in the case of vacuum brazing where the stainless steel with the hard oxide film formed on the surface is brazed at low temperature, and the flux can not be used. ;CONSTITUTION: The Sn base brazing filler metal of low melting point having the composition consisting of, by weight, 0.05-1.5% P, 0.5-5.0% Ni, if required, ≤30% Cu and/or ≤10% Ag, and 35% the total addition of Ni, Cu and Ag, and the balance Sn with inevitable impurities is provided. This brazing filler metal is excellent in the flowability.;COPYRIGHT: (C)1996,JPO
