Title (EN) BRAZING SHEET
(FR) FEUILLE DE BRASAGE
Abstract: front page image
(EN)The invention concerns a brazing sheet comprising a core layer (5) and a braze cladding, said core layer (5) being aluminium or an aluminium alloy, said braze cladding comprising (a) a flux composite layer(2), which flux composite layer comprises a matrix of aluminium or an aluminium alloy, said matrix containing flux particles; (b) at least one filler alloy layer (1) not containing flux particles; and, (c) an aluminium or aluminium alloy layer (3) not containing flux particles, said layer forming the outermost surface of at least one side of the brazing sheet, wherein the flux composite layer (a) is positioned between said filler alloy layer (b) and said aluminium or aluminium alloy layer (c). The invention further concerns a method for its manufacturing, a cladding plate, use of the brazing sheet and a brazed heat exchanger.
(FR)L'invention concerne une feuille de brasage comprenant une couche centrale (5) et un placage de brasage, ladite couche centrale (5) étant en aluminium ou un alliage d'aluminium, ledit placage de brasage comprenant (a) une couche composite de flux (2), laquelle couche composite de flux comprenant une matrice d'aluminium ou d'un alliage d'aluminium, ladite matrice contenant des particules de flux ; (b) au moins une couche d'alliage de charge (1) ne contenant pas de particules de flux ; et (c) une couche en aluminium ou alliage d'aluminium (3) ne contenant pas de particules de flux, ladite couche formant la surface la plus à l'extérieur d'au moins un côté de la feuille de brasage, la couche composite de flux (a) étant positionnée entre ladite couche d'alliage de charge (b) et ladite couche d'aluminium ou d'alliage d'aluminium (c). L'invention concerne également un procédé pour sa fabrication, une plaque de placage, l'utilisation de la feuille de brasage et un échangeur thermique brasé.
