CR004A Copper vs. CC498K Bronze

Both CR004A copper and CC498K 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 CR004A copper and the bottom bar is CC498K bronze.
