Ti-3Al-2.5V (Grade 9) Titanium AlloyTi-3Al-2.5V (Grade 9) Titanium Alloy

Titanium Grade 9 is sometimes referred to as 'half 6-4'. This alloy of titanium with 3% aluminium and 2.5% vanadium offers 20 to 50% greater mechanical strength than the commercially pure (CP) titanium grades, but is more formable and weldable than Ti-6Al-4V (Grade 5).

Titanium Grade 18 (UNS R56322) is identical to Grade 9 in all respects with the exception of the additional 0.04 – 0.08% palladium to increase corrosion resistance. Titanium Grades 9 and 18 have a density of 4.48 g/cc - less than 60% that of steel.

Corrosion Resistance:

This material offers good corrosion resistance in oxidising, neutral and mildly reducing media, including chlorides. Titanium Grade 18 with the addition of palladium offers greater resistance to corrosion. The alloy resists oxidation up to 600°F (316°C).
