PROBLEM TO BE SOLVED: To provide a brazing sheet of an aluminum alloy, which has enhanced brazability compared to that of a conventional one while keeping strength after having been brazed, workability, corrosion resistance and the like at a predetermined level or higher.SOLUTION: The brazing sheet 1 of the aluminum alloy has a two-layered structure in which a brazing filler metal 3 is provided on one side of a core material 2. The core material 2 includes, by mass%, 0.6-1.0% Si, 0.6-1.0% Cu, 0.7-1.8% Mn, 0.1-0.7% Mg, 0.06-0.20% Ti and the balance Al with unavoidable impurities. The brazing filler metal 3 is made of an aluminum alloy which includes 3.0-12.0 mass% Si. The sheet thickness of the brazing sheet 1 of the aluminum alloy is 0.6-1.4 mm. The area rate of a {001} plane on the surface of the core material 2 is 0.3 or more. |
