Abstract

L'invention concerne un matériau d'ailette en alliage d'aluminium qui comprend un alliage d'aluminium contenant de 1,50 à 5,00 % en masse de Si, le reste étant constitué d'Al et d'impuretés inévitables, qui se présente sous une couche unique et qui possède des capacités de liaison thermique. Dans une section transversale dans le sens de l'épaisseur du matériau d'ailette, le diamètre de cercle équivalent des particules de Si est représenté par D, la distance de la couche de surface au centre des particules de Si est représentée par L, l'épaisseur du matériau d'ailette est représentée par t et la longueur parallèle à la couche de surface est représentée par W. Toutes les particules de Si qui sont présentes dans la plage de la longueur W et qui sont telles que D ≥ L et L + D > 0,04t satisfont à la relation : 0 ≤ ΣπD2 < 0,08tW. La feuille de brasage en alliage d'aluminium selon l'invention comporte le matériau d'ailette en tant que matériau de revêtement, le matériau d'ailette étant plaqué sur un matériau d'âme en alliage d'aluminium. L'échangeur de chaleur selon l'invention utilise le matériau d'ailette ou la feuille de brasage pour une ailette.
