# UNS N06250 Nickel Alloy

N06250 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. It has a moderately high ductility among the wrought nickels in the database.

The graph bars on the material properties cards below compare N06250 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.
