Solder Alloy 601 vs. Solder Alloy 714

Both solder alloy 601 and solder alloy 714 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 48% of their average alloy composition in common. There are 21 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is solder alloy 601 and the bottom bar is solder alloy 714.
