More Information
Summary:An aluminum alloy fin material for heat exchangers, the aluminum alloy fin material being made of aluminum alloy comprising: 1.00 to 1.60 mass % of Mn; 0.70 to 1.20 mass % of Si; 0.05 to 0.50 mass % of Fe; 0.05 to 0.35 mass % of Cu; and 1.00 to 1.80 mass % of Zn, with the balance being Al and inevitable impurities, in which a matrix of the aluminum alloy has a fibrous structure, and tensile strength thereof is 170 to 230 MPa. According to the present invention, an aluminum alloy fin material for heat exchangers having excellent formability before brazing, excellent brazing properties, and excellent strength properties and corrosion resistance after brazing can be provided.
