As-cast C82600 Copper vs. As-cast C99750 Brass

Both as-cast C82600 copper and as-cast C99750 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 59% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is as-cast C82600 copper and the bottom bar is as-cast C99750 brass.
