Grade CX2MW (N26022) Cast Nickel
Grade CX2MW nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the heat treated (HT) condition. CX2MW is the ASTM designation for this material. N26022 is the UNS number. It has a moderately high ductility and a moderately high tensile strength among cast nickels.
The graph bars on the material properties cards below compare grade CX2MW 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.
