Japanese Patent JP2017172011
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aluminum alloy brazing sheet excellent in not only corrosion resistance in a sacrificial anode material, but also corrosion resistance in a brazing material side and further excellent in strength after brazing and moldability.SOLUTION: The aluminum alloy brazing sheet 1 has a core material 2, a sacrificial anode material 3 and a brazing material 4, a calculated by a=C×erf(t/55), where Cis content of the sacrificial anode material 3, tis thickness of the sacrificial anode material 3, tis thickness of the brazing material 4 and t is thickness of the aluminum alloy brazing sheet 1, is 1.0 to 5.0 and b calculated by b=0.5×C×{erf((t-t+t)/55)+erf((t+t-t)/55)} is 1.00 or less.SELECTED DRAWING: Figure 1
