Abstract

An inner grooved tube for heat exchangers is formed of a copper alloy, wherein the copper alloy includes 0.004 to 0.040 mass% of P, with the balance being Cu and unavoidable impurities , and has a recrystallized texture that has a Goss orientation density of more than 0 and 3.2 or less. A method for producing an inner grooved tube for heat exchangers includes sequentially performing a casting step, a hot extrusion step, a cold working step, an intermediate annealing step, a roll forming step, and a final annealing step, or sequentially performing a casting step, a cold working step, an intermediate annealing step, a roll forming step, and a final annealing step, wherein the casting step casts a copper alloy that includes 0.004 to 0.040 mass% of P, with the balance being Cu and unavoidable impurities, and the outer diameter reduction ratio during working performed between the intermediate annealing step and the final annealing step is 6 to 16%. An inner grooved tube for heat exchangers that exhibits excellent bendability can thus be provided.
