Solder Alloy 714 vs. Solder Alloy 801

Both solder alloy 714 and solder alloy 801 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 714 and the bottom bar is solder alloy 801.
