CC333G Bronze vs. CR020A Copper

Both CC333G bronze and CR020A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 80% 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 CC333G bronze and the bottom bar is CR020A copper.
