Working properties during production, structure, and physicomechanical properties of alloy 1441 sheets of the system Al–Cu–Mg–Li are described, making it possible to prepare thin sheets up to 0.3 mm thick by a coiled cold rolling method. Medium-strength (σu = 450 MPa) alloy 1441 sheet is distinguished by lower density (2.6 g/cm3), increased stiffness (E = 79 GPa), and it is used effectively in promising layered aluminum-polymer materials of the FML class for aviation structures.
