CR022A Copper vs. CC331G Bronze

Both CR022A copper and CC331G bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 85% 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 CR022A copper and the bottom bar is CC331G bronze.
