CR014A Copper vs. C86800 Bronze

Both CR014A copper and C86800 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 55% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is CR014A copper and the bottom bar is C86800 bronze.
