Title Ballistic Evaluation of 7085 Aluminum.
Publication Date Mar 2012
Media Count 66p
Personal Author D. Gallardy
Abstract The U.S. Army Research Laboratory (ARL) evaluated the ballistic performance of two tempers of aluminum alloy (AA) 7085 produced by Alcoa. The tempers included a high-strength variant, 7085-T7E01, for utilization as an appliqu against direct-fire threats and a lower strength, higher ductility variant, 7085-T7E02, for underbody blast protection kits. Ballistic evaluation was performed using armor-piercing and fragment-simulating projectiles to determine the V50 ballistic protection limit (V50) for various thicknesses of each temper. The V50 was then compared to other ballistic-grade aluminum alloys, namely AA7039 and AA2139. The results of these tests were used to derive the acceptance tables included in the new military specification, MIL-DTL-32375(MR), created for AA7085.
