Abstract: A process for brazing of aluminium magnesium alloys is described applying a flux which comprises KAlF4 or CsAlF4 or both as major constituent. The flux further comprises at least one alkaline or alkaline earth metal compound selected from the group consisting of KAlF4, CsAlF4, Li3AlF6, CaF2, CaCO3, MgF2, MgCO3, SrF2, SrCO3, BaF2, and BaCO3. Preferably the flux comprises or consists of KAlF4, CsAlF4, and Li3AlF6 and optionally contains also BaF2.
