摘要：
In the brazing of aluminum a flux composed of a mixture of alkali metal fluoaluminates, with or without admixed AlF.sub.3, is employed. The flux has a composition of AlF.sub.3 about 53-62%, KF about 35-44%, and LiF about 2-7%, in terms of simple compounds. The flux has a liquidus temperature in the range of 490.degree.-560.degree. C. depending on its actual composition. The flux is of particular utility when brazing aluminum containing 0.4-2% magnesium and/or having a low solidus temperature and is preferably employed in an atmosphere of a dry, inert gas.
