<P>PROBLEM TO BE SOLVED: To provide an aluminum alloy laminated plate and a laminated plate subjected to heating corresponding to brazing, each of which is excellent in fatigue characteristics and capable of reducing thickness of laminated plate subjected to heating corresponding to brazing, such as an aluminum alloy radiator tube, or a laminated plate such as an aluminum alloy brazing sheet. <P>SOLUTION: The aluminum alloy laminated plate or a laminated plate subjected heating corresponding to brazing is composed of at least a core aluminum alloy sheet 2 and an anticorrosive aluminum alloy sacrifice material 3 cladded thereon. The core aluminum alloy sheet 2 has a specified 3000-series composition, and the average number density of specifically sized dispersed particles of the core aluminum alloy sheet 2 is regulated so as to impart better fatigue characteristics dominated by crack formation. <P>COPYRIGHT: (C)2009,JPO&INPIT |
