ACI-ASTM CA15M Steel vs. Grade CU5MCuC Nickel

ACI-ASTM CA15M steel belongs to the iron alloys classification, while grade CU5MCuC nickel belongs to the nickel alloys. They have 45% of their average alloy composition in common. There are 26 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 ACI-ASTM CA15M steel and the bottom bar is grade CU5MCuC nickel.
