CR011A Copper vs. C92800 Bronze

Both CR011A copper and C92800 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 80% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is CR011A copper and the bottom bar is C92800 bronze.
