CR020A Copper vs. CC330G Bronze

Both CR020A copper and CC330G bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 90% 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 CR020A copper and the bottom bar is CC330G bronze.
