EN CC380H (CuNi10Fe1Mn1-C) Copper-Nickel
CC380H copper-nickel is a copper-nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. CC380H is the EN numeric designation for this material. CuNi10Fe1Mn1-C is the EN chemical designation.
It has a fairly high electrical conductivity among cast copper-nickels. In addition, it has the highest ductility and a moderately high thermal conductivity.
The graph bars on the material properties cards below compare CC380H 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.

Alloy Composition
Among cast copper alloys, the composition of CC380H copper-nickel is notable for containing comparatively high amounts of nickel (Ni) and iron (Fe). Nickel is used to improve strength (particularly at elevated temperatures) and corrosion resistance. It also creates the need for additional care during casting. Iron is used to increase strength inexpensively.
