Title:
ALUMINUM ALLOY BRAZING SHEET
Document Type and Number:
WIPO Patent Application WO/2018/216773
Kind Code:
A1
Abstract:
This aluminum alloy brazing sheet is provided with: a core material comprising 2.0 mass% or less (including 0 mass%) of Mg and a remainder of Al and unavoidable impurities; and a brazing material comprising Si, Bi, Mg, and a remainder of Al and unavoidable impurities. The aluminum alloy brazing sheet satisfies the expressions 3 ≤ CSi ≤ 13, 0.13CMg
-0.3 ≤ CBi ≤ 0.58CMg
0.45, CMg-b ≥ 0.1, and 0.2 ≤ CMg ≤ 1.1 when the Si content of the brazing material is denoted by CSi, the Bi content of the brazing material is denoted by CBi, the Mg content of the brazing material is denoted by CMg-b, the Mg content of the core material is denoted by CMg-c, and CMg = CMg-b + CMg-c / 2.
