Solder Alloy 703 vs. Grade 702C Zirconium
Both solder alloy 703 and grade 702C zirconium are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 17 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 703 and the bottom bar is grade 702C zirconium.
