Description
Titanium Gr5-ELI Target, also known as Titanium Grade 23, is a titanium alloy composed of 6% aluminium, 4% vanadium, and extra low interstitial (ELI) elements.
It is derived from the standard Ti-6Al-4V alloy (Grade 5) but with
tighter controls on oxygen, nitrogen, carbon, and iron content,
providing superior toughness and fracture resistance.
Titanium Gr23 offers excellent corrosion resistance, high specific strength, and outstanding biocompatibility, making it the preferred titanium alloy for medical implants, aerospace structures, and high-performance engineering applications.
