Solder Alloy 122 vs. Grade 705C Zirconium
Both solder alloy 122 and grade 705C zirconium are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 18 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is solder alloy 122 and the bottom bar is grade 705C zirconium.
