Grade CX2M (N26059) Cast Nickel
Grade CX2M nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the heat treated (HT) condition. CX2M is the ASTM designation for this material. N26059 is the UNS number. It has the highest ductility among the cast nickels in the database.
The graph bars on the material properties cards below compare grade CX2M nickel to: cast 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.
