Solder Alloy 115 vs. Solder Alloy 136

Both solder alloy 115 and solder alloy 136 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 90% of their average alloy composition in common. There are 24 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 115 and the bottom bar is solder alloy 136.
