Grade 702C Zirconium vs. Solder Alloy 181
Both grade 702C zirconium and solder alloy 181 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 16 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is grade 702C zirconium and the bottom bar is solder alloy 181.
