Title:
ALUMINIUM ALLOY FIN MATERIAL FOR HEAT EXCHANGER EXCELLENT IN STRENGTH AND CORROSION RESISTANCE AFTER BRAZING
Document Type and Number:
Japanese Patent JP2013040367
Kind Code:
A
Abstract:
To provide an aluminium alloy fin material for a heat exchanger excellent in brazing property and strength after brazing and also excellent in intergranular corrosion resistance property.
This aluminium alloy fin material includes 1.0-2.0 mass% Mn, 0.5-1.3 mass% Si, 0.1-0.8 mass% Fe, over 0.20 mass% to 0.4 mass% Cu, 1.1 mass% to less than 2.0 mass% Zn, and the balance being Al and inevitable impurities. This aluminium alloy fin material excellent in the strength after brazing and corrosion resistance is characterized in that a matrix of the aluminium alloy fin material has a recrystallized structure.
