CR007A Copper vs. C55180 Copper

Both CR007A copper and C55180 copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 95% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is CR007A copper and the bottom bar is C55180 copper.
