EN 2.4889 (NiCr28FeSiCe) Nickel Alloy
EN 2.4889 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 2.4889 is the EN numeric designation for this material. NiCr28FeSiCe is the EN chemical designation.
It has a moderately low embodied energy among wrought nickels. In addition, it has a moderately high heat capacity and a moderately low base cost.
The graph bars on the material properties cards below compare EN 2.4889 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.
