SOLDERLESS ALUMINUM BRAZING

Disclosed is a method for the brazing of aluminium wherein the addition of solder is no longer necessary. To this effect a flux is used containing 6-50 wt % potassium fluorosilicate and 50-94 wt % potassium fluoroaluminate. The flux can, for example, be applied in the form of an aqueous suspension.
