# UNS N06920 Nickel Alloy

N06920 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. The graph bars on the material properties cards below compare N06920 nickel 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.
