TC4 ELI (Ti-6Al-4V ELI) is an ultra-low interstitial element grade variant of Ti-6Al-4V titanium alloy, specifically developed for demanding applications requiring extremely high fracture toughness and fatigue resistance. By strictly limiting the content of impurities such as oxygen, nitrogen, and hydrogen (e.g., O ≤ 0.13wt%, Fe ≤ 0.25wt%), it significantly enhances the material's plasticity, low-temperature toughness, and crack growth resistance. It is particularly suitable for critical aerospace structures and medical implants.
Key Features and Technical Parameters
• Maximum Dimensions and Weights
Fully customized production is supported. Specific dimensions (bar/plate/forging) and weight limits are determined based on the end-use design requirements and are subject to a feasibility assessment of the processing technology.
• Packaging Specifications
Ingress Protection: Packed in industrial-grade wooden crates, internal components are enclosed in moisture-proof, sealed bags treated with vacuum or inert gas to protect the material from environmental corrosion, mechanical damage, and impurity contamination during storage and transportation.
• Core Application Industries
1. Aerospace: Aircraft engine fan discs, high-pressure compressor rotors, critical load-bearing fasteners, landing gear components, and spacecraft cryogenic fuel tanks, relying on their high specific strength, low-temperature toughness, and fatigue resistance.
2. Biomedical: Orthopedic implants (acetabular cups, femoral stems), spinal fixation systems, and trauma repair devices, complying with ASTM F136 standards and demonstrating excellent biocompatibility and long-term in vivo stability.
3. Marine Engineering: Submersible pressure hulls and seawater piping systems, leveraging their resistance to seawater corrosion and high strength and toughness.
4. High-End Equipment: Load-bearing components for competitive equipment and precision instrument structures, meeting the dual requirements of lightweighting and high reliability.
5. Other Industries: Specialized equipment components requiring reliability in extreme environments.
