EN 1.3961 Alloy vs. Grade CW6MC Nickel

EN 1.3961 alloy belongs to the iron alloys classification, while grade CW6MC nickel belongs to the nickel alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is EN 1.3961 alloy and the bottom bar is grade CW6MC nickel.
