CR008A Copper vs. CC484K Bronze

Both CR008A copper and CC484K bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 86% 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 CR008A copper and the bottom bar is CC484K bronze.
