CR011A Copper vs. C91000 Bronze

Both CR011A copper and C91000 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 85% 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 CR011A copper and the bottom bar is C91000 bronze.
