description PROBLEM TO BE SOLVED: To provide a copper alloy material for a pipe having high strength and high conductivity.SOLUTION: A method for manufacturing the copper alloy material for the pipe includes: a casting step of casting a billet containing 0.05-0.25 wt.% iron (Fe), 0.01-0.05 wt.% manganese (Mn), 0.015-0.07 wt.% phosphorus (P), and the balance being copper (Cu), while satisfying the weight ratio (Fe/P) of iron (Fe) to phosphorus (P) being 0.75-6.0; a hot extruding step of obtaining a pipe stock by hot-extruding the billet; a cold pipe-rolling step of obtaining a pipe material by cold-pipe-rolling the hot-extruded pipe stock; a cold drawing step of cold-drawing the cold-rolled pipe material; a level winding step of winding the cold-drawn pipe material into a coil; and a heat treatment step of subjecting the pipe material, which is wound into a coil, to a heat treatment.
