Abstract

Procédé pour la préparation d'alliages à base de cuivre durci par précipitation selon le brevet principal. On soumet l'alliage de Cu-Ti, de Cu-Be ou à base de Cu-Ni donnant lieu à une précipitation homogène et continue de particules cohérentes lors du durcissement par précipitation à un travail à chaud à une température de finissage supérieure à 400 degrés C, on le recuit ensuite en solution à une température de 650 à 1100 degrés C pendant une durée de 10 secondes à 24 heures et on le refroidit à la température ambiante à une vitesse inférieure à 650 degrés C par minute. L'alliage de cuivre selon l'invention convient tout spécialement à la fabrication de contacts électriques.
