Nickel Alloy 333 (N06333)

Nickel 333 is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. N06333 is the UNS number for this material. Nickel Alloy 333 is the common industry name.

It has a moderately low tensile strength among the wrought nickels in the database.

The graph bars on the material properties cards below compare nickel 333 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.
