CR014A Copper vs. CC481K Bronze

Both CR014A copper and CC481K bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 88% 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 CR014A copper and the bottom bar is CC481K bronze.
