Grade 23 ELI Titanium/Aluminum/Vanadium Alloy Disk (Ti90/Al6/V4)

Grade 23 ELI Titanium/Aluminum/Vanadium Alloy Disk (Ti90/Al6/V4) is defined by its extra-low interstitial (ELI) composition, providing superior toughness, corrosion resistance, and exceptional biocompatibility compared to standard Grade 5 alloys. Its refined microstructure ensures improved fatigue performance and crack resistance, which is critical in both biomedical and aerospace environments. This alloy disk is widely used in aerospace, medical device manufacturing, and high-performance engineering sectors, where reliability under cyclic loading and corrosive conditions is essential. Specific applications include load-bearing orthopedic implants such as hip and spinal devices, aerospace structural disks, and high-stress chemical processing components. In research, Grade 23 ELI alloy disks are central to the study of fatigue mechanisms, corrosion resistance, and advanced surface modification strategies for implants. The balance of mechanical resilience, corrosion protection, and biological compatibility ensures their ongoing importance in scientific innovation and demanding industrial applications.
