Annealed and Age Hardened (AT or TF00) Ni-Be 360

Annealed and age hardened alloy 360 is nickel beryllium 360 in the annealed and aged condition. The graph bars on the material properties cards below compare annealed and age hardened 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.
