Solder Alloy 713 vs. Solder Alloy 201

Both solder alloy 713 and solder alloy 201 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 95% 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 713 and the bottom bar is solder alloy 201.
