摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy fin material for heat exchangers which can secure brazeability, sacrificial anode effect, and high temperature bucking resistance and has excellent formability with slight winding curl.;SOLUTION: An aluminum alloy fin material for heat exchangers, which has a heating binding function as a single layer, is made of an aluminum alloy having a predetermined alloy composition, has a thickness t of 0.02 to 0.20 mm, a ratio YS/TS of 0,2% bearing force YS (MPa) and the tensile strength TS (MPa) of 0.75 to 0.99, a ratio t/YS (mm/MPa) of a thickness t and 0.2% bearing force of 0.00012 to 0.00300. An aluminum alloy fin material coil for hear exchangers obtained by winding the aluminum alloy fin material for heat exchangers in coil, a corrugate fin material produced by using the aluminum alloy fin material for heat exchangers or aluminum alloy fin material coil for heat exchangers, and heat exchangers produced with these corrugate fin materials.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
