Abstract
A brazing sheet formed of an aluminum alloy and exhibiting excellent post-brazing strength, corrosion resistance and brazability with a thickness of less than 200 μm is provided. The brazing sheet includes a core layer, a filler layer of an Al—Si based alloy on one side of the core layer, and a sacrificial layer on the other side of the core layer. The core layer includes more than 1.5 mass % and 2.5 mass % or less of Cu, 0.5 mass % to 2.0 mass % of Mn, Al, and inevitable impurities. The sacrificial layer includes 2.0 mass % to 7.0 mass % of Zn, more than 0.10 mass % and 3.0 mass % or less of Mg, Al, and inevitable impurities. The filler layer and the sacrificial layer each have a thickness of 15 μm to 50 μm. A total clad rate of the filler layer and the sacrificial layer is equal to or less than 50%.
