Abstract

See full text

A highly corrosion resistant and highly formable aluminum-alloy clad material, a method for producing the same, a heat exchanger using the same and a method for producing the same are shown. The present aluminum-alloy clad material has an aluminum alloy core material, an intermediate layer material clad on one surface of the core material and a brazing filler metal clad on the surface of the intermediate layer material that is not on the core material side, wherein a crystal grain size of the intermediate layer material before brazing heating is 60 μm or more, and in a cross section of the core material in a rolling direction before brazing heating, when R1 (μm) represents the crystal grain size in a plate thickness direction, and R2 (μm) represents the crystal grain size in the rolling direction, R1/R2 is 0.30 or less.
