Gr5 Ti-6Al-4V ELI (Extra Low Interstitial) is a commonly used aluminum-vanadium-titanium alloy in the medical field, specifically designed for implantable devices and long-term implants. Its chemical composition is primarily titanium, with alloying elements comprising approximately 6% Al and 4% V. The content of interstitial elements such as oxygen, nitrogen, and carbon is strictly controlled to improve toughness and ductility, ensuring safety and stability during long-term use within the human body. Common forms include forged bars, cold-drawn bars, or annealed bars, with surfaces that can be polished, pickled, or anodized to meet various medical requirements.
