Grade CU5MCuC Nickel vs. SAE-AISI H25 Steel

Grade CU5MCuC nickel belongs to the nickel alloys classification, while SAE-AISI H25 steel belongs to the iron alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is grade CU5MCuC nickel and the bottom bar is SAE-AISI H25 steel.
