AWS BAu-3 vs. AWS BAg-8a

Both AWS BAu-3 and AWS BAg-8a are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much.

For each property being compared, the top bar is AWS BAu-3 and the bottom bar is AWS BAg-8a.
