EN 1.4805 Stainless Steel vs. C97800 Nickel Silver

EN 1.4805 stainless steel belongs to the iron alloys classification, while C97800 nickel silver belongs to the copper alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.4805 stainless steel and the bottom bar is C97800 nickel silver.
