C92700 Bronze vs. CC494K Bronze

Both C92700 bronze and CC494K bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 90% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is C92700 bronze and the bottom bar is CC494K bronze.
