Solder Alloy 801 vs. Solder Alloy 714

Both solder alloy 801 and solder alloy 714 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 91% of their average alloy composition in common. There are 23 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is solder alloy 801 and the bottom bar is solder alloy 714.
