Annealed 80-silver 20-cadmium-oxide vs. Annealed 85-platinum 15-iridium

Both annealed 80-silver 20-cadmium-oxide and annealed 85-platinum 15-iridium are otherwise unclassified metals. Both are furnished in the annealed condition. There are 8 material properties with values for both materials. Properties with values for just one material (11, 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 annealed 80-silver 20-cadmium-oxide and the bottom bar is annealed 85-platinum 15-iridium.
