ASTM Grade HN Steel vs. C96600 Copper

ASTM grade HN steel belongs to the iron alloys classification, while C96600 copper belongs to the copper alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 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 ASTM grade HN steel and the bottom bar is C96600 copper.
