A fluoride flux for silver brazing comprises an iron powder, a cobalt powder, a nickel powder or a copper powder which has an average diameter of 1-100.mu. in a flux having a main component such as an alkali metal fluoride, an alkali fluoroborate, an alkali metal chloride, an alkali metal borate, etc..

Flux for brazing

Substrates made of a metal or an alloy are bonded by coating a brazing flux incorporating a metallic powder or a metal compound powder on the surface of the substrate having a melting point of higher than 700.degree. C.; and heating them at a temperature higher than a melting point of the flux but lower than a melting point of the metal of the metallic powder or the metal compound powder whereby a molten crystallization and a mutual diffusion are caused between the substrates and the metal activated by the molten flux.
