CC332G Bronze vs. CR018A Copper

Both CC332G bronze and CR018A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 83% 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 CC332G bronze and the bottom bar is CR018A copper.
