Cold Worked Monel K-500
Cold worked Monel K-500 is Monel K-500 in the cold worked (strain hardened) condition. It has the highest strength and lowest ductility compared to the other variants of Monel K-500. The graph bars on the material properties cards below compare cold worked Monel K-500 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.
