Abstract

Aluminum thin plates which are used as fins of a heat exchanger can be manufactured, as described in the claims, by controlling the composition of an aluminum alloy, which is used as a core material, and controlling the cold rolling reduction ratio of a clad material composed of the core material and a skin material, after hot rolling. The thus manufactured aluminum thin plates for brazing are excellent in high-temperature sagging resistance and sacrificial anodic effect, whereby it is possible to make the fins thinner.
