Solder Alloy 111 vs. Solder Alloy 124

Both solder alloy 111 and solder alloy 124 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 52% 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 111 and the bottom bar is solder alloy 124.
