AWS BVAg-29 vs. AWS BAu-1
Both AWS BVAg-29 and AWS BAu-1 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 24% of their average alloy composition in common, which, by itself, doesn't mean much.
For each property being compared, the top bar is AWS BVAg-29 and the bottom bar is AWS BAu-1.
