ABSTRACT A method of joining aluminium components by means of an aluminium brazing alloy having a melting point lower than that of the aluminium components, in which the assembled components are heated to a temper- ature above the melting point of the brazing alloy and below the melting point of said components in the presence of a potassium fluoaluminate flux, which is essentially free of unreacted KF characterised in that the flux and the brazing alloy is applied to the surface of at least one of the components as an aqueous slurry of finely divided flux and metal powder, the film is then dried and the components are brazed (after assembly, if necessary) by heating in a dry, oxygen-free inert gas atmosphere, the application of flux/brazing alloy slurry being controlled to apply 40-150 gms/m2 of solids And the flux:brazing alloy ratio being selected to deposit at least 5 gms/m2 of flux. -1-
