Abstract
L'invention porte sur un alliage comprenant du cuivre, du nickel, de l'étain et, facultativement, du phosphore, lequel alliage peut être utilisé dans, par exemple, un tube d'alliage de cuivre pour échangeurs de chaleur. Cet alliage assure une excellente résistance à la rupture et une excellente aptitude au traitement, ce qui permet de réduire le poids du tube et permet son utilisation dans des applications à haute pression, avec des fluides de refroidissement tels que du dioxyde de carbone.
