ARMOR TITANIUM
Ti-6Al-4V ELI-LC Sheets & Plates for Next‑Generation Ballistic Systems
Titanium changes the mass budget for armor design. At barely 60% of the density of steel yet with comparable yield strength, 6Al-4V ELI enables designers to hit weight targets that used to require exotic composites — while retaining the metal’s innate ductility, multi‑hit survivability, structural rigidity, and field‑repairability. Adept has spent years tuning titanium alloys for the Mantis™, Storm™, and other plate programs, and we now offer that know‑how in flat product form.
The result is Ti-6Al-4V ELI-LC: The lightest practical metallic strike‑face you can buy, already battle‑proven.
Adept’s Modified “ELI‑LC” Chemistry
Standard ASTM Grade 23 already specifies low interstitials, which increases toughness and ductility over standard Ti6Al4V. To boost performance further, we go one step beyond. Adept’s in‑house melt route tightens the carbon specification to ≤ 0.03 wt % (vs. 0.08 % in conventional Grade 23) while holding oxygen below 0.11 wt %. Lower carbon means fewer carbide colonies and a tougher, cleaner alpha matrix — exactly what you want for thin‑gauge strike faces that must survive edge hits and repeated abuse.
Why Titanium?
Superior specific strength.
6Al‑4V ELI‑LC (~4.43 g/cm³) delivers >150 ksi (~1 GPa) tensile strength in the annealed condition, providing a specific strength that eclipses quenched steels.
High strain‑rate performance.
Under ballistic loading the alloy work‑hardens and sheds energy without shattering, so damage remains local and structures don’t suffer from extensive cracking.
Corrosion & temperature resilience.
A tenacious TiO2 film resists salt spray and battlefield contaminants; properties are retained from -196°C cryogenic service up to ~350°C.
Toughness & weldability.
The ELI-LC chemistry pushes fracture toughness even higher, important for high-impact structural applications, and particularly in appliqué panels that see flexure, and it’s also weldable.
Stock Program
Our “ready‑to‑ship” blanks are sized expressly for body‑armor prototyping and small‑run projects. All other dimensions are cut from master plate or ordered hot‑rolled/forged to spec.

Custom Orders – Thicknesses from 2 mm up to 25 mm and larger sheet/plate formats (up to 1000 × 3000 mm) are available on 4‑ to 6‑week lead times.
Processing & Services
Adept runs the same in‑house workflow that produces our titanium strike‑faces and body‑armor blanks: water‑jet or abrasive‑jet cutting, 3‑axis and 5‑axis CNC contouring, hot‑press forming, electron‑beam edge welding, and ballistic coupon testing to NIJ 0108.01 and STANAG 4569. We also provide adhesive bonding kits for hybrid ceramic/metal or Ti/PE laminate construction.
Typical Applications
Specialty body armor applications (thin strike-faces, interlayers, ductile stiffening liners).
Add‑on spall liners for armored vehicles and maritime craft.
Fragment‑suppressing door and bulkhead panels in aircraft.
High‑end shields and anti‑blast inserts.
Structural elements in robotics or UAVs for enhanced strength and impact resistance at a lower modulus than carbon fiber.
Ordering & Logistics
Material ships from either our EU facility or our US depot, vacuum‑wrapped with interleaves. Standard lead time: 2 weeks ex‑works for stock blanks; 8-9 weeks for non‑stock gauges or custom geometries. We can accommodate nested prototype cuts; send a DXF or STEP file and we’ll optimize for lowest scrap.
