C87200 Bronze vs. CR025A Copper

Both C87200 bronze and CR025A copper 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 C87200 bronze and the bottom bar is CR025A copper.
