7021 Aluminum vs. 90-silver 10-cadmium-oxide

7021 aluminum belongs to the aluminum alloys classification, while 90-silver 10-cadmium-oxide belongs to the otherwise unclassified metals. There are 8 material properties with values for both materials. Properties with values for just one material (22, 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 7021 aluminum and the bottom bar is 90-silver 10-cadmium-oxide.
