Solder Alloy 114 vs. Solder Alloy 142

Both solder alloy 114 and solder alloy 142 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 89% 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 114 and the bottom bar is solder alloy 142.
