AWS BVAg-8b vs. ASTM B477 Au-Ni-Ag

Both AWS BVAg-8b and ASTM B477 Au-Ni-Ag are otherwise unclassified metals. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 15 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is AWS BVAg-8b and the bottom bar is ASTM B477 Au-Ni-Ag.
