Solder Alloy 132 vs. Solder Alloy 182

Both solder alloy 132 and solder alloy 182 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is solder alloy 132 and the bottom bar is solder alloy 182.
