Military & Defense
Defense and military programs demand materials that perform under the most demanding conditions — high strength, tight tolerances, full traceability, and zero compromise on quality. Taiwan Ye Fong Aluminium has been supplying defense-grade aluminum to approved vendor lists of major defense primes for years, including RAFAEL Advanced Defense Systems, ELBIT Systems, and IAI (Israel Aerospace Industries).
Our manufacturing capabilities cover the full process chain in-house: extrusion, cold drawing, heat treatment, straightening, and non-destructive testing. Every order is backed by AS9100D and NADCAP certifications, with full material traceability from billet to finished product.
Defense Aluminum Alloys Materials We Supply
- 7075 (T6 / T651 / T7351 / T73511)
The most widely specified alloy in defense structural applications. Exceptional strength-to-weight ratio with good resistance to stress corrosion. Used in missile bodies, weapon system structures, UAV Structural frames & landing gear and load-bearing systems, and armored vehicle components.
- 7050 (T7451 / T7651)
Preferred for thick-section applications where resistance to stress corrosion cracking is critical. Common in defense plate and heavy structural bar.
- 2024 (T3 / T351 / T851)
High fatigue strength alloy used in airframe structures, tie rods, and defense system components requiring excellent toughness.
- 2014 (T4 / T6)
High-strength alloy used in forging stock and structural components for military aircraft and defense equipment.
- 5083 (H112 / H116 / H321 / H131)
The standard alloy for naval and marine defense applications, including armored vehicle hulls and marine vessel structures.
Defense Applications
- Missile & Munitions Structures
We supply 7075 and 2024 aluminum seamless tube and bar for missile body structures and munitions components, produced to tight dimensional tolerances with full NDT inspection and material certification.
- UAV & USV Structural Components
Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicles (USV) require lightweight, high-strength aluminum with consistent mechanical properties. We supply extruded and drawn tube, bar, and profile in 7075 and 2024 for UAV/USV frame and structural applications. Explore UAV &USV aluminum applications more detail here.
