Cold Worked Nickel Alloy 200
Cold worked nickel 200 is nickel 200 in the cold worked (strain hardened) condition. It has the highest strength and lowest ductility compared to the other variants of nickel 200. The graph bars on the material properties cards below compare cold worked 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.
