Abstract
(EN)
Provided are a brazing sheet for a heat exchanger fin and a manufacturing method for the brazing sheet such that the brazing sheet exhibits excellent self-corrosion resistance, high-temperature buckling resistance, and formability. The brazing sheet has a core material and a brazing material laminated on the core sheet. The core material has a chemical composition containing 0.50 to 2.0 mass% of Mn, 0.050 to 0.60 mass% of Si, 0.050 to 0.70 mass% of Fe, and the balance Al and inevitable impurities, and said core material has a fibrous structure. The brazing material has a chemical composition containing 6.0 to 13 mass% of Si, more than 0 mass% to 0.80 mass% of Fe, and the balance Al and inevitable impurities. The brazing sheet has a total elongation of 3% or greater, a necking/total elongation ratio of 0.35 to 0.95, and a yield strength of 100 to 200 MPa. The metal structure of the core material has the property of changing into a recrystallized structure having an average crystal grain size exceeding 200 µm when held at a temperature of 600˚C for three minutes.

Cette invention concerne une tôle de brasage pour une ailette d'échangeur de chaleur et un procédé de fabrication de la tôle de brasage de telle sorte que la tôle de brasage présente une résistance à la corrosion, une résistance au flambage à haute température et une aptitude au formage excellentes. La tôle de brasage a un matériau d'âme et un matériau de brasage stratifié sur l'âme. Le matériau d'âme a une composition chimique contenant de 0,50 à 2,0 % en masse de Mn, de 0,050 à 0,60 % en masse de Si, de 0,050 à 0,70 % en masse de Fe, le reste étant de l'Al et les inévitables impuretés, et ledit matériau d'âme ayant une structure fibreuse. Le matériau de brasage a une composition chimique contenant 6,0 à 13 % en masse de Si, plus de 0 % en masse à 0,80 % en masse de Fe, le reste étant de l'Al et les inévitables impuretés. La tôle de brasage a un allongement total supérieur ou égal à 3 %, un rapport de striction/allongement total de 0,35 à 0,95, et une limite d'élasticité de 100 à 200 MPa. La structure métallique du matériau d'âme a la propriété de se transformer en une structure recristallisée ayant une taille moyenne de grain cristallin supérieure à 200 µm lorsqu'elle est maintenue à une température de 600 °C pendant trois minutes.
