C94300 Bronze vs. Solder Alloy 115

C94300 bronze belongs to the copper alloys classification, while solder alloy 115 belongs to the otherwise unclassified metals. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is C94300 bronze and the bottom bar is solder alloy 115.
