CC212E Bronze vs. CC755S Brass

Both CC212E bronze and CC755S brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 62% of their average alloy composition in common. There are 27 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is CC212E bronze and the bottom bar is CC755S brass.
