CR015A Copper vs. C87200 Bronze

Both CR015A copper and C87200 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 94% 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 CR015A copper and the bottom bar is C87200 bronze.
