Nickel Alloy 200 (2.4066, N02200, NA11)

Nickel 200 is a nickel alloy formulated for primary forming into wrought products. 2.4066 is the EN numeric designation for this material. NA11 is the British Standard (BS) designation. N02200 is the UNS number. And Nickel Alloy 200 is the common industry name.

It can have a fairly low tensile strength among the wrought nickels in the database.

The properties of nickel 200 include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare nickel 200 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.
