Abstract
The present invention relates to an aluminum alloy for fins of heat exchangers such as of automobile radiators and evaporators comprising 0.3 to 1.0% by weight of silicon, 0.3 to 3.0% by weight of iron, and the balance of aluminum and unavoidable impurities, which is readily workable for a fin (or readily corrugated), and is less deformed by brazing heat, and yet has improved thermal conductivity after the brazing.
