# UNS N07041 (2.4973) Nickel Alloy

N07041 nickel is a nickel alloy formulated for primary forming into wrought products. 2.4973 is the EN numeric designation for this material. N07041 is the UNS number. It has a fairly high tensile strength and a moderately low ductility among wrought nickels.

The graph bars on the material properties cards below compare N07041 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.
