ASTM B477 Au-Ni-Ag vs. K93600 Alloy

ASTM B477 Au-Ni-Ag belongs to the otherwise unclassified metals classification, while K93600 alloy belongs to the iron alloys. There are 15 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is ASTM B477 Au-Ni-Ag and the bottom bar is K93600 alloy.
