UNS N07752 Nickel Alloy
N07752 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the aged (precipitation hardened) condition. It has a moderately high tensile strength and a moderately low ductility among wrought nickels.
The graph bars on the material properties cards below compare N07752 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.
