Patent ID: 8283049

Claim:
An aluminum brazing sheet consisting of: a core material made of an aluminum alloy; a cladding material cladded on one side of the core material; and a brazing material laminated on the side of the core material opposite to the cladding material; wherein a potential of the cladding is lower than a potential of the core and a sacrificial anode effect is obtained, the cladding material is an aluminum alloy consisting of from 0.52 to 0.7 mass % of Mg, 0.5 to 1.5 mass % of Si, 0.4 to 1.2 mass % of Mn, 0.3 to 6 mass % of Zn, Al, and the core material consists of: 0.3 to 0.7 mass % of Si, 0.6 to 1.2 mass % of Mn, 0.5 to 1.0 mass % of Cu, a maximum of 0.3 mass % Mg, from 0.15 to 0.2 mass % Ti, from 0.1 to 0.15 mass % Cr, and Al.
