BRAZING SHEET FORMED FROM ALUMINUM ALLOY

摘要

Provided is a brazing sheet formed from an aluminum alloy, which is capable of maintaining excellent strength after brazing and corrosion resistance even if reduced in the thickness. This brazing sheet 1A is provided with: a core material 2; a brazing filler material 4 that is arranged on at least one surface side of the core material 2; and an intermediate layer 3 that is arranged between the core material 2 and the brazing filler material 4 arranged on at least one surface side. The core material 2 contains 0.50-1.10% by mass of Cu, 0.10-1.10% by mass of Si and 0.60-2.00% by mass of Mn, with the balance made up of Al and unavoidable impurities. The intermediate layer 3 contains 0.50-10.00% by mass of Zn and more than 0.20% by mass but 1.10% by mass or less of Si, with the balance made up of Al and unavoidable impurities. The brazing filler material 4 is formed from an AlSi alloy.
