Grade CY40 Nickel vs. AWS BNi-10

Both grade CY40 nickel and AWS BNi-10 are nickel alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 79% 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 grade CY40 nickel and the bottom bar is AWS BNi-10.
