Nickel Alloy 600 (N06600, NA14)

Nickel 600 is a nickel alloy formulated for primary forming into wrought products. NA14 is the British Standard (BS) designation for this material. N06600 is the UNS number. Nickel Alloy 600 is the common industry name. Additionally, the AFNOR (French) designation is NC15Fe.

This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.

The properties of nickel 600 include four 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 600 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.
