Abstract: Articles of aluminum, or of an aluminum alloy, can be brazed satisfactorily, employing an aluminum alloy as the brazing material, by removing any surface oxide layers from bodies comprising the articles, and preforms of the brazing material, simultaneously with providing initial films of zinc, or tin, thereon. Then coatings of silver and/or of gold, or a suitable alloy containing silver or gold, are provided on the articles, and on the preforms of the brazing material, to protect the surfaces of these aluminum containing bodies from reoxidizing. The required brazing operation then is performed in a high vacuum, or in an inert atmosphere. Any oxygen produced inadvertently, for example, by the decomposition of any silver oxide present, is removed before it can contact any aluminum. The zinc or tin, the materials of the coatings, and the aluminum of the bodies, interdiffuse, and this interdiffusion proceeds rapidly when the brazing alloy melts.
