Solder Alloy 116 vs. Solder Alloy 151

Both solder alloy 116 and solder alloy 151 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 62% of their average alloy composition in common. There are 23 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is solder alloy 116 and the bottom bar is solder alloy 151.
