UNS N10675 (2.4600, NiMo29Cr) Nickel Alloy
N10675 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 2.4600 is the EN numeric designation for this material. NiMo29Cr is the EN chemical designation. And N10675 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 the lowest heat capacity among wrought nickels. In addition, it has a moderately high embodied energy and a moderately high base cost.
The graph bars on the material properties cards below compare N10675 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.
