As-cast C82400 Copper vs. As-cast C94700 Bronze

Both as-cast C82400 copper and as-cast C94700 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 27 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 as-cast C82400 copper and the bottom bar is as-cast C94700 bronze.
