UNS N06603 Nickel-Chromium Alloy
N06603 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition.
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 high heat capacity and a moderately low ductility among wrought nickels.
The graph bars on the material properties cards below compare N06603 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.
