C94300 Bronze vs. Solder Alloy 142

C94300 bronze belongs to the copper alloys classification, while solder alloy 142 belongs to the otherwise unclassified metals. They have a modest 30% 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 (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 142.
