CR012A Copper vs. CC380H Copper-nickel

Both CR012A copper and CC380H copper-nickel 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 CR012A copper and the bottom bar is CC380H copper-nickel.
