Abstract: The US Army Research Laboratory evaluated the ballistic performance of aluminum alloys (AAs) 7056-T761, 7056-T751, and 7056-T721 produced by Constellium. Ballistic evaluation was performed using armor-piercing and fragment-simulating projectiles to determine the V50 ballistic-protection limit (V50) for various thicknesses of material. The V50 was then compared with other ballistic-grade AAs, namely AA7085-T711 and AA7085-T721. The results of these experiments were used to validate the acceptance tables for AA7085 and AA7056 included in the updated military specification, MIL-DTL-32375A (MR).
