Grade N7M Nickel vs. Grade CU5MCuC Nickel

Both grade N7M nickel and grade CU5MCuC nickel are nickel alloys. Both are furnished in the heat treated (HT) condition. They have 47% of their average alloy composition in common. There are 25 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is grade N7M nickel and the bottom bar is grade CU5MCuC nickel.
