Title:
ALUMINUM ALLOY SHEET AND METHOD FOR PRODUCING SAME, AND HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/176420
Kind Code:
A1
Abstract:
Disclosed is an aluminum alloy sheet composed of a single layer and having a function to be bonded by heating, the aluminum alloy sheet being characterized by comprising an aluminum alloy containing 1.50 to 5.00% by mass of Si, 0.01 to 2.00% by mass of Fe, 0.50 to 2.00% by mass of Mn and a remainder comprising Al and unavoidable impurities, in which, in a heating test where the temperature is risen from 300°C to 400°C at an average temperature rising rate of 60°C/min. or less and the temperature is maintained at 600 ± 3°C for 5 ± 3 minutes, the average crystal grain diameter on a plane parallel to a rolled surface after the heating test is 370 μm or more and the average number of crystal grains in the thickness direction after the heating test is 1.5 grains or more. According to the present invention, it is possible to provide an aluminum alloy sheet which is composed of a single layer and has a function to be bonded by heating, and which has high deformation resistance during the bonding by heating.
