时效硬化合金在熔化焊后热影响区的强度明显降低。铝锌镁合金也不例外,但是,这类合金能在室温下时效硬化,使强度部分恢复。通过焊后人工高溫时效,也能夠达到比较高的强度。英国陆军采用铝锌鎂合金制造的装备主要有军用工程车(CEF)和蝎式/狐式系列的轻型装甲车辆,都釆用了抗弹级的铝合金装甲板。中型桁架桥(MGB)和水陆两用桥(M2)是 The age hardening alloy in the heat affected zone after welding significantly reduced the intensity. Aluminum-zinc-magnesium alloy is no exception, but such alloys can age hardening at room temperature, the strength of the part recovered. After welding artificial aging, but also able to achieve higher strength. British Army used aluminum-zinc-magnesium alloy equipment mainly military engineering vehicles (CEF) and scorpion / fox series of light armored vehicles, preclude the use of anti-bomb grade aluminum armor plate. Medium Truss Bridge (MGB) and amphibious bridge (M2) are
