Wire titanium alloy 6-4 ELI™

Ti-6Al-4Vgrade 23aerospace

ATI Ti-6Al-4V-ELI, Grade 23 alloy (Extra Low Interstitials, UNS R56407) is a higher purity grade of ATI Ti-6Al-4V alloy. This grade has lower oxygen, carbon, and iron content. It is used in biomedical applications such as surgical instruments, orthopedic implants,and is the preferred grade for marine and cryogenic applications, and some important aerospace components. This titanium grade is produced by vacuum arc primary melting followed by a second vacuum arc remelting operation.
