Abstract

There is provided an aluminum alloy brazing sheet having an improved brazability than in the related art while keeping the post-braze strength, workability, corrosion resistance, and the like at respective prescribed or higher levels. An aluminum alloy brazing sheet has a two-layered structure in which on one side of a core material, a brazing material is provided. The core material contains Si: 0.6 to 1.0 mass %, Cu: 0.6 to 1.0 mass %, Mn: 0.7 to 1.8 mass %, Mg: 0.1 to 0.7 mass %, and Ti: 0.06 to 0.20 mass %, and the balance including Al and inevitable impurities. The brazing material includes an aluminum alloy containing Si: 3.0 to 12.0 mass %, the gage of the aluminum alloy brazing sheet is 0.6 to 1.4 mm, and the area ratio of a {001} plane in the core material surface is 0.3 or more.
