EN CC382H (CuNi30Cr2FeMnSi-C) Copper-Nickel

CC382H copper-nickel is a copper-nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CC382H is the EN numeric designation for this material. CuNi30Cr2FeMnSi-C is the EN chemical designation.

It has a moderately high heat capacity among the cast copper-nickels in the database.

The graph bars on the material properties cards below compare CC382H copper-nickel to: cast copper-nickels (top), all copper 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.
