Overview of ERTi-23 (Ti-6Al-4V ELI) Titanium Alloy Welding Wire
ERTi-23 is an extra-low interstitial (ELI) grade of Ti-6Al-4V welding wire equivalent to ASTM Grade 23 (UNS R56401) and ASTM F136 for surgical implants. It provides superior fracture toughness, excellent biocompatibility, and enhanced fatigue strength compared to standard Grade 5, while maintaining high strength. With its proven reliability in the most critical applications, ERTi-23 is the primary choice for surgical implants like joint replacements and bone plates, as well as for high-integrity aerospace components requiring maximum damage tolerance.
