Solder Alloy 704 vs. Grade 704C Zirconium

Both solder alloy 704 and grade 704C 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 704 and the bottom bar is grade 704C zirconium.
