ASTM B477 Au-Ni-Ag vs. 60Pd-40Ag Alloy
Both ASTM B477 Au-Ni-Ag and 60Pd-40Ag alloy are otherwise unclassified metals. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is ASTM B477 Au-Ni-Ag and the bottom bar is 60Pd-40Ag alloy.
