AWS BNi-7 vs. Grade M35-2 Nickel

Both AWS BNi-7 and grade M35-2 nickel are nickel alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 67% of their average alloy composition in common. There are 19 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is AWS BNi-7 and the bottom bar is grade M35-2 nickel.
