Abstract

Disclosed is a heat-transfer pipe (2) having excellent corrosion resistance and fewer occurrences of crushed fin. Also, the pipe (2) can be made thinner. Provided is an aluminum-alloy-made heat-transfer pipe (2) with inner surface grooves, comprising 0.8 to 1.8% by mass (hereinafter, the term "% by mass" is referred to as %) of Mn and 0.1 to 0.6% of Mg, wherein the remainder consists of Al and unavoidable impurities; and a plurality of elongated fins (9) are formed on the inner surface of the pipe (2). The most illustrative drawing is FIG. 4.
