Grey Cast Iron vs. EN 2.4815 Cast Nickel

Grey cast iron belongs to the iron alloys classification, while EN 2.4815 cast nickel belongs to the nickel alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is grey cast iron and the bottom bar is EN 2.4815 cast nickel.
