CC331G Bronze vs. CR024A Copper

Both CC331G bronze and CR024A copper 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 CC331G bronze and the bottom bar is CR024A copper.
