Document Type and Number:
WIPO Patent Application WO/2022/004460
Kind Code:
A1
Abstract:
This aluminum alloy cladding material has a sacrificial material disposed on both surfaces of a core material. The composition of the core material contains, in terms of mass%, 0.7-1.8% of Mn, 0.3-1.3% of Si, 0.05-0.7% of Fe and 0.5-3.0% of Zn, with the remainder comprising Al and unavoidable impurities. The composition of the sacrificial material contains, in terms of mass%, 0.005-0.7% of Mn, 0.05-0.3% of Fe and 1.0-4.0% of Zn, with the remainder comprising Al and unavoidable impurities. The Zn content in the sacrificial material is at least 0.2 mass% higher than the Zn content in the core material. The potential of the core material after a brazing heat treatment is -700 to 870 mV.
