CR024A Copper vs. CC495K Bronze

Both CR024A copper and CC495K bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 79% 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 CR024A copper and the bottom bar is CC495K bronze.
