"Who said aluminum is weak?"
ECO-Almag is now redefining the standard for lightweight and high-strength materials in defense.
ECO-Almag offers ballistic performance up to five times superior to that of conventional aluminum, enhancing light and composite armor capabilities and increasing the competitiveness of weapon systems.
Even with high strength, conventional aluminum has poor impact absorption, making it prone to fracture or cracking under bullet or shrapnel impact.
In contrast, ECO-Almag has high elongation, fine-grained microstructure, and enhanced impact dispersion due to increased magnesium content, allowing it to absorb ballistic energy over a wider area and delay fracture.
In actual ballistic tests, differences of more than 4 to 5 times were observed in fracture area after penetration, residual impact depth on the rear side, delamination degree, and crack propagation range.
Ballistic performance can be evaluated using the CVN indicator. CVN (Charpy Impact Value) represents the quantified energy absorption in joules (J), and is a key metric for evaluating ballistic materials, protective components, and impact-resistant structural materials. A higher CVN value means the material can absorb more energy without breaking, with slower crack propagation and greater resistance to fracture.
ECO-Almag surpasses the limitations of conventional aluminum with its high strength, high elongation, and excellent corrosion resistance, offering the lightweight, durability, and reliability demanded by the defense industry.
Comparison of Eco-Almag’s Suitability as a Ballistic Material
CVN (Charpy V-Notch) is an indicator of impact toughness.
The unit is joules (J), and the test is conducted using a Charpy impact tester. A V-notch is made in the sample, which is then struck with a hammer to measure the energy absorbed at fracture. A higher value indicates better resistance to impact and less likelihood of breakage, making it advantageous for ballistic and defense structural applications.

“Military-grade' Aluminum”
포드(Ford)는 자사 2015년형 F-150 트럭의 마케팅에서 ‘군용 등급 알루미늄(Military-grade aluminum)’이라는 문구를 사용했습니다.이 트럭은 5xxx 및 열처리된 6xxx 시리즈 알루미늄 바디를 채택했으며,강도, 충돌 보호, 내식성 측면에서 강철과 동등하거나 뛰어난 성능을 발휘한다는 점을 강조하기 위함이었습니다.
Eco-Almag offers true competitiveness as a next-generation material that meets all three critical requirements for military-grade aluminum alloys: strength, corrosion resistance, and impact resistance.
This is the "Aluminum Armor Plate" page from the thyssenkrupp website. It clearly states that aluminum alloys such as 5083 and 7085 are being supplied to the defense industry.
The U.S. Army's Bradley Fighting Vehicle is also protected by 5xxx and 7xxx series aluminum alloys. In military environments, top-tier corrosion resistance and impact resistance are essential.
Comparison of Surface Oxidation and Corrosion Properties of Eco-Almag
Eco-Almag maintains oxidation stability despite increased magnesium content, making it highly suitable for components requiring excellent corrosion resistance, such as in marine environments or unmanned submersibles.
Immersion-Type Battery Case for Naval Vessels – ECO-Almag as the Perfect Alternative
For immersion-type battery packs used in military and commercial marine equipment, preventing seawater ingress and leakage is a critical requirement. However, conventional aluminum materials are structurally difficult to form as a single integrated unit, making it challenging to completely eliminate the risk of leakage.
ECO-Almag has overcome these limitations as a next-generation material for naval defense applications. The development and performance evaluation of battery pack products using Almag have been completed, and full-scale production mold development began in May 2025.
ECO-Almag offers approximately five times better heat dissipation than steel and enables weight reduction of up to 80 tons per vessel, significantly enhancing both the efficiency and safety of naval ships and maritime weapon systems.
Enabling seamless, integrated battery forming that was not possible with conventional materials, ECO-Almag fundamentally eliminates the risk of leakage in marine environments.
