# Annealed (A or TB00) Ni-Be 360

Annealed alloy 360 is nickel beryllium 360 in the annealed condition. It has the lowest strength and highest ductility compared to the other variants of nickel beryllium 360. The graph bars on the material properties cards below compare annealed alloy 360 to: wrought nickels (top), all nickel alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
