Annealed Monel K-500
Annealed Monel K-500 is Monel K-500 in the annealed condition. It has the lowest strength compared to the other variants of Monel K-500. The graph bars on the material properties cards below compare annealed Monel K-500 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.
