摘要： An armor component produced from a 7xxx series aluminum alloy, wherein the aluminum alloy consists essentially of: - 8.4 wt.% ≤ Zn ≤ 10.5 wt.%; - 1.3 wt.% ≤ Mg ≤ 2 wt.%; - 1.2 wt.% ≤ Cu ≤ 2 wt.%; - at least one dispersoid forming element with a total dispersoid forming element content higher than 0.05 wt.%; - the remainder substantially aluminum, incidental elements and impurities; wherein the 7XXX alloy is in the form of a plate having a thickness of 0.5 - 3 inches; wherein the 7XXX alloy is over-aged to achieve: (i) a fragment simulated particles V50 ballistic limit such that: V50 (FSP 20mm) > 1633 T2 - 1479 T + 1290 where T is the thickness plate (unit: inch) and the unit of V50 is feet/s. (ii) an armor piercing V50 ballistic limit such that: V50 (0.30cal AP M2) > -282 T2 + 1850 T + 610 where T is the thickness plate (unit: inch) and the unit of V50 is feet/s.
