C73500 Nickel Silver vs. ACI-ASTM CN7MS Steel
C73500 nickel silver belongs to the copper alloys classification, while ACI-ASTM CN7MS 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 22 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is C73500 nickel silver and the bottom bar is ACI-ASTM CN7MS steel.
