Abstract (en)
[origin: EP3521463A1] Provided is a corrosion resistant copper tube which can exhibit a further improved resistance to ant nest corrosion, and which is suitably usable as a heat transfer tube and refrigerant tube in air-conditioning equipment and refrigerating equipment. The copper tube is formed of a copper material consisting of 0.15-0.6% by weight of phosphorus and the balance being copper and impurities, and has electric conductivity (Y1 or Y2: %IACS) which satisfies 50-75X ≤ Y1 ≤ 60-75X in the case where the tube includes a recrystallized structure, or 47-75X ≤ Y2 ≤ 57-75X in the case where the tube includes a deformation structure, wherein X (% by weight) represents a content of phosphorus.
