| description | PROBLEM TO BE SOLVED: To secure good brazing property and to secure high strength by preventing degradation in the strength after brazing, in a plate fin material for a heat exchanger.SOLUTION: In the plate fin material which has sheet thickness of 0.05-0.15 mm, in which joint portion is formed and heat transfer pipe is brazed to the joint portion, and which is composed of a single material or a clad material, the core material of the single material or clad material has a composition composed of, by mass%, >1.5 to 2.0% Mn and 0.15-0.50% Fe wherein Mn and Fe contents satisfy a condition of 3.5≤Mn/Fe≤10.0, and the balance Al with inevitable impurities. After brazing and heat treatment, a portion except for the joint portion has ≥50% subgrain structure in an area ratio in the cross-sectional structure and the joint portion has at ≤50% subgrain structure in an area ratio in the cross-sectional structure. |
