CR016A Copper vs. AWS ERNiCu-7
CR016A copper belongs to the copper alloys classification, while AWS ERNiCu-7 belongs to the nickel alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 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 CR016A copper and the bottom bar is AWS ERNiCu-7.
