Abstract

Disclosed is a heat-transfer pipe having excellent corrosion resistance and fewer occurrences of crushed fin. Also, the pipe can be made thinner.Provided is an aluminum-alloy-made heat-transfer pipe with inner surface grooves, comprising 0.8 to 1.8% by mass (hereinafter, the term "% by mass" is referred to as %) of Mn, 0.3 to 0.8% of Cu, and 0.3 to 1.0% of Si, wherein the remainder consists of AI and unavoidable impurities; and a plurality of elongated fins are formed on the inner surface of the pipe.
