Extra Low Interstitial Titanium Alloy for Medical Implants & High-Purity Critical Applications
Overview
Grade 23 Titanium, also known as Ti-6Al-4V ELI (Extra Low Interstitial), is a high-purity, low-carbon version of Grade 5 titanium alloy offered by BOZE Metal, specifically engineered for medical implant, aerospace, and high-purity critical applications. With extremely low levels of interstitial elements (carbon, oxygen, nitrogen), this grade offers superior biocompatibility, enhanced toughness, improved ductility, and excellent fatigue resistance compared to standard Grade 5 titanium, making it the gold standard for surgical implants and high-performance critical components.
Fully certified to medical and aerospace material standards, Grade 23 (Ti-6Al-4V ELI) is widely used in orthopedic implants, dental devices, surgical instruments, and high-purity aerospace components. BOZE Metal supplies medical-grade Grade 23 titanium with full traceability, and custom precision implant components are available through BOZO CNC-Ti specialized medical machining services.
