CC330G Bronze vs. C87700 Bronze

Both CC330G bronze and C87700 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 90% 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 CC330G bronze and the bottom bar is C87700 bronze.
