CR022A Copper vs. C90500 Gun Metal

Both CR022A copper and C90500 gun metal 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 28 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 CR022A copper and the bottom bar is C90500 gun metal.
