Grade 20 Cast Iron vs. N08024 Nickel

Grade 20 cast iron belongs to the iron alloys classification, while N08024 nickel belongs to the nickel alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is grade 20 cast iron and the bottom bar is N08024 nickel.
