UNS N06985 (2.4619) Nickel Alloy

N06985 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 2.4619 is the EN numeric designation for this material. N06985 is the UNS number.

It has a moderately low melting temperature among the wrought nickels in the database.

The graph bars on the material properties cards below compare N06985 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.
