CC496K Bronze vs. Solder Alloy 117

CC496K bronze belongs to the copper alloys classification, while solder alloy 117 belongs to the otherwise unclassified metals. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is CC496K bronze and the bottom bar is solder alloy 117.
