EN 2.4632 Nickel vs. Nickel 685

Both EN 2.4632 nickel and nickel 685 are nickel alloys. Both are furnished in the aged (precipitation hardened) condition. They have a moderately high 95% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is EN 2.4632 nickel and the bottom bar is nickel 685.
