Solder Alloy 101 vs. Solder Alloy 117

Both solder alloy 101 and solder alloy 117 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 57% of their average alloy composition in common. There are 24 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 solder alloy 101 and the bottom bar is solder alloy 117.
