EN 1.3961 Alloy vs. Nickel 686
EN 1.3961 alloy belongs to the iron alloys classification, while nickel 686 belongs to the nickel alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is EN 1.3961 alloy and the bottom bar is nickel 686.
