EN 2.4663 (NiCr23Co12Mo) Nickel Alloy

EN 2.4663 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 2.4663 is the EN numeric designation for this material. NiCr23Co12Mo is the EN chemical designation.

The graph bars on the material properties cards below compare EN 2.4663 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.
