Abstract: Magnesium containing aluminum alloys can be brazed by using a flux mixture or a flux composition comprising a potassium fluoroaluminate which is essentially present as monopotassium tetrafluoroaluminate. The flux mixture or flux composition further contains a magnesium-compatibilizing agent, e.g. a cesium fluoroaluminate or potassium or cesium fluorozincates.
