Cold Worked Monel R-405
Cold worked Monel R-405 is Monel R-405 in the cold worked (strain hardened) condition. It has the highest strength and lowest ductility compared to the other variants of Monel R-405. The graph bars on the material properties cards below compare cold worked Monel R-405 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.
