C97800 Nickel Silver vs. ACI-ASTM CK3MCuN Steel

C97800 nickel silver belongs to the copper alloys classification, while ACI-ASTM CK3MCuN steel belongs to the iron alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. 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 C97800 nickel silver and the bottom bar is ACI-ASTM CK3MCuN steel.
