Aluminum alloy foam for energy absorption member

摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy foam in which more deformation progresses in a state of a plateau stress being kept low and can provide excellent protection properties for pedestrians (leg).;SOLUTION: The aluminum alloy foam which is installed in front of a bumper beam and is suitable for an energy-absorbing member such as a protection member for pedestrians is produced by foaming an aluminum alloy comprising, by mass%, 0.5 to 20.0% Zn, 0.1 to 5.0% Ca, 0.1 to 5.0% Ti, 0.1 to 5.0% Mg, further at least one element of 0.1 to 5.0% Ag and 0.1 to 5.0% Zr, and the balance aluminum with unavoidable impurities.;COPYRIGHT: (C)2008,JPO&INPIT
