C94500 Bronze vs. Solder Alloy 134

C94500 bronze belongs to the copper alloys classification, while solder alloy 134 belongs to the otherwise unclassified metals. They have a modest 26% 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 C94500 bronze and the bottom bar is solder alloy 134.
