Solder Alloy 104 vs. Solder Alloy 116

Both solder alloy 104 and solder alloy 116 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 70% 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 104 and the bottom bar is solder alloy 116.
