The Ballistic and Corrosion Evaluation of Magnesium Elektron E675 vs. Baseline Magnesium Alloy AZ31B and Aluminum Alloy 5083 for Armor Applications

reportActive / Technical Report | Accession Number: ADA550614 | Open PDF

Abstract:

The U.S. Army Research Laboratory has evaluated the ballistic and corrosion performance of high-strength magnesium alloy Elektron 675 for use in vehicle and personnel protection. The performance of Elektron 675 is compared to baseline magnesium alloy AZ31B and baseline aluminum alloy 5083 AA5083. While Mg alloy E675 offers a higher ballistic protection at equal weight, Elektron 675 did not pass the corrosion resistance requirement specified in military specification MIL-DTL-32333. The areal density and cost will also need to be addressed for consideration as an armor material.
