UNS N06650 (2.4850) Nickel Alloy
N06650 nickel is a nickel alloy formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 2.4850 is the EN numeric designation for this material. N06650 is the UNS number.
It has a moderately high ductility among wrought nickels. In addition, it has a moderately high melting temperature and a moderately high tensile strength.
The graph bars on the material properties cards below compare N06650 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.
