CC380H Copper-nickel vs. CR021A Copper

Both CC380H copper-nickel and CR021A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 87% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is CC380H copper-nickel and the bottom bar is CR021A copper.
