UNS N06200 (2.4675, NiCr23Mo16Cu) Nickel Alloy
N06200 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 2.4675 is the EN numeric designation for this material. NiCr23Mo16Cu is the EN chemical designation. And N06200 is the UNS number.
This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.
It has a moderately high ductility and a moderately high melting temperature among wrought nickels.
The graph bars on the material properties cards below compare N06200 nickel to: wrought 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.
