Precipitation Hardened (+P1080) 2.4878 Nickel Alloy
EN 2.4878 +P1080 nickel is EN 2.4878 nickel in the aged (precipitation hardened) condition. The graph bars on the material properties cards below compare EN 2.4878 +P1080 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.
