Grade CW6MC Nickel vs. ASTM F15 Fe-Ni-Co

Grade CW6MC nickel belongs to the nickel alloys classification, while ASTM F15 Fe-Ni-Co belongs to the iron alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is grade CW6MC nickel and the bottom bar is ASTM F15 Fe-Ni-Co.
