CR012A Copper vs. C90200 Bronze

Both CR012A copper and C90200 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 93% 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 CR012A copper and the bottom bar is C90200 bronze.
