UNS N08120 (2.4854) Nickel Alloy
N08120 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 2.4854 is the EN numeric designation for this material. N08120 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 low embodied energy among wrought nickels. In addition, it has a moderately low base cost and a moderately high heat capacity.
The graph bars on the material properties cards below compare N08120 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.
