Abstract
El procedimiento comprende el recubrimiento y la difusion térmica de una aleacion a base de Sn un nucleo a base de Cu, con lo que se forma un material composite constituido por un nucleo a base de Cu, una superficie externa constituida por una aleacion a base de Sn y una capa intermedia constituida por aleaciones Cu-Sn de composiciones variables. Dicho material composite formado es adecuado para la fabricacion de aletas para intercambiadores de calor, particularmente radiadores para automoviles, cuyos panales pueden soldarse en un horno con atmosfera oxidante o no oxidante.
