AWS BAg-7 vs. Grade 705C Zirconium

Both AWS BAg-7 and grade 705C zirconium are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 13 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is AWS BAg-7 and the bottom bar is grade 705C zirconium.
