Solder Alloy 113 vs. Solder Alloy 502
Both solder alloy 113 and solder alloy 502 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 45% of their average alloy composition in common. There are 22 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 113 and the bottom bar is solder alloy 502.
