Ti-6AL-4V Titanium Alloy

The titanium alloy Ti-6AL-4V (also known as Ti 6-4) is generally comprised of 88% – 90% of titanium (Ti), 6% aluminum (Al), and 4% of vanadium (V). Trace amounts of other components that make of Ti 6-4 would be nitrogen (N), carbon (C), oxygen (O), iron (Fe) and hydrogen (H). The UNS code for Ti6-4 is UNS R56400.

Ti 6-4 forged parts are sought after for many applications because of their high tensile strength and for having a high resistance to many corrosive elements, especially against saltwater.
