Abstract
(EN)
A brazing sheet (1) according to the present invention comprises: a core material (11) which is formed of an Al alloy that contains 0.20-3.0% by mass of Mg; and a brazing filler material (12) which is formed of an Al alloy that contains Mg, 6.0-13.0% by mass of Si and more than 0.050% by mass but 1.0% by mass or less of Bi, and which is superposed on at least one surface of the core material (11), while being exposed in the outermost surface (121). The brazing filler material (12) has an Mg distribution wherein the Mg concentration continuously decreases from the boundary surface (122) at the boundary with the core material (11) toward the outermost surface (121). The Mg concentration at a position (P1/8) where the depth from the outermost surface (121) is 1/8 of the thickness (tf) of the brazing filler material (12) is 0.150% by mass or less; and the Mg concentration at a position (P7/8) where the depth from the outermost surface (121) is 7/8 of the thickness (tf) of the brazing filler material is 5-90% of the Mg amount in the core material (11).

La présente invention concerne une feuille de brasage (1) comprenant : un matériau de noyau (11) qui est formé d'un alliage d'Al qui contient de 0,20 à 3,0 % en masse de Mg ; et un matériau de charge de brasage (12) qui est formée d'un alliage d'Al qui contient du Mg, 6,0 à 13,0 % en masse de Si et plus de 0,050 % en masse mais pas plus de 1,0 % en masse de Bi, et qui est superposé sur au moins une surface du matériau de noyau (11), tout en étant exposé dans la surface le plus à l'extérieur (121). Le matériau de charge de brasage (12) a une distribution de Mg dans laquelle la concentration en Mg diminue en continu depuis la surface limite (122) au niveau de la limite avec le matériau de noyau (11) vers la surface le plus à l'extérieur (121). La concentration en Mg à une position (P1/8) où la profondeur à partir de la surface le plus à l'extérieur (121) représente 1/8 de l'épaisseur (tf) du matériau de remplissage de brasage (12) est de 0,150 % en masse ou moins ; et la concentration en Mg à une position (P7 /8) où la profondeur à partir de la surface le plus à l'extérieur (121) représente 7/8 de l'épaisseur (tf) du matériau de remplissage de brasage est de 5 à 90 % de la quantité de Mg dans le matériau de noyau (11).
