CC382H Copper-nickel vs. CC763S Brass

Both CC382H copper-nickel and CC763S brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 65% of their average alloy composition in common. There are 27 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is CC382H copper-nickel and the bottom bar is CC763S brass.
