Nickel Alloy 890 (N08890)
Nickel 890 is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. N08890 is the UNS number for this material. Nickel Alloy 890 is the common industry name.
It has a moderately high heat capacity among wrought nickels. In addition, it has a moderately low tensile strength and a moderately low base cost.
The graph bars on the material properties cards below compare nickel 890 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.
