Grade 20 Cast Iron vs. N09777 Nickel

Grade 20 cast iron belongs to the iron alloys classification, while N09777 nickel belongs to the nickel alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is grade 20 cast iron and the bottom bar is N09777 nickel.
