CC140C Copper vs. CR007A Copper

Both CC140C copper and CR007A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. Their average alloy composition is basically identical. 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 CC140C copper and the bottom bar is CR007A copper.
