Solder Alloy 104 vs. CC496K Bronze

Solder alloy 104 belongs to the otherwise unclassified metals classification, while CC496K bronze belongs to the copper alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is solder alloy 104 and the bottom bar is CC496K bronze.
