Commercially Pure Zinc vs. Solder Alloy 123

Commercially pure zinc belongs to the zinc alloys classification, while solder alloy 123 belongs to the otherwise unclassified metals. 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 commercially pure zinc and the bottom bar is solder alloy 123.
