CC212E Bronze vs. CR007A Copper

Both CC212E bronze and CR007A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 73% 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 CC212E bronze and the bottom bar is CR007A copper.
