85-platinum 15-iridium vs. AWS BVAg-8b

Both 85-platinum 15-iridium and AWS BVAg-8b are otherwise unclassified metals. There are 15 material properties with values for both materials. Properties with values for just one material (5, 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 85-platinum 15-iridium and the bottom bar is AWS BVAg-8b.
