Titanium 23 / 6Al 4V Eli - UNS R56401
Titanium Grade 23 is also known as Ti-6AL-4V-ELI or simply Ti 6-4 ELI. ELI is short for "Extra Low Interstitials". Grade 23 is very similar to Grade 5 except Grade 23 has lower oxygen, nitrogen and iron. The lower interstitials provide more ductility and better fracture toughness (slightly less strength) than Grade 5
