AWS BAg-8a vs. AWS BVAu-2
Both AWS BAg-8a and AWS BVAu-2 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much.
For each property being compared, the top bar is AWS BAg-8a and the bottom bar is AWS BVAu-2.
