EN 2.4642 (NiCr29Fe) Nickel Alloy
EN 2.4642 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 2.4642 is the EN numeric designation for this material. NiCr29Fe is the EN chemical designation.
It has a moderately high heat capacity among the wrought nickels in the database.
The graph bars on the material properties cards below compare EN 2.4642 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.
