Ti 6Al-6V-2Sn | UNS R56620 – Eastern Titanium

Material Overview

The Ti 6-6-2 Alloy (UNS R56620) presents a trade-off between increased strength and decreased weldability and toughness compared to the more commonly used Ti-6Al-4V alloy. Its use is recommended in high-strength applications where welding is not critical, and the material’s limitations can be accommodated, such as airframe and jet engine parts, rocket engine cases, and ordnance components.
