Titanium
Commercially pure titanium (Grades 1–4) and Ti-6Al-4V alloy (Grade 5): light, strong and immune to corrosion in seawater and oxidising chlorides.
Titanium grades
- Titanium Grade 1Titanium Grade 1 (UNS R50250) is the softest, most ductile commercially pure titanium, with the lowest oxygen content and excellent formability and corrosion resistance.
- Titanium Grade 2Titanium Grade 2 (UNS R50400) is the workhorse commercially pure titanium, combining moderate strength, good weldability and outstanding corrosion resistance in seawater, chlorides and oxidising media.
- Titanium Grade 3Titanium Grade 3 (UNS R50550) is a higher-strength commercially pure titanium, used where more strength than Grade 2 is needed with similar corrosion resistance.
- Titanium Grade 4Titanium Grade 4 (UNS R50700) is the strongest commercially pure titanium, used for airframe, marine and medical parts needing high strength with CP-titanium corrosion resistance.
- Titanium Grade 5Titanium Grade 5 (Ti-6Al-4V, UNS R56400) is the most widely used titanium alloy, with aluminium and vanadium giving about three times the strength of CP titanium at 4.43 g/cm³.
