Grade CU5MCuC (N08826) Cast Nickel

Grade CU5MCuC nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the heat treated (HT) condition. CU5MCuC is the ASTM designation for this material. N08826 is the UNS number. It has the lowest base cost among the cast nickels in the database.

The graph bars on the material properties cards below compare grade CU5MCuC 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.
