AWS BAu-3 vs. Solder Alloy 162

Both AWS BAu-3 and solder alloy 162 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 15 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is AWS BAu-3 and the bottom bar is solder alloy 162.
