C83600 Ounce Metal vs. C93200 Bronze

Both C83600 ounce metal and C93200 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 98% of their average alloy composition in common. There are 28 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 C83600 ounce metal and the bottom bar is C93200 bronze.
