CR012A Copper vs. CC493K Bronze

Both CR012A copper and CC493K bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 83% 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 CC493K bronze.
