357.0 Aluminum vs. 60Pd-40Ag Alloy

357.0 aluminum belongs to the aluminum alloys classification, while 60Pd-40Ag alloy belongs to the otherwise unclassified metals. There are 21 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 357.0 aluminum and the bottom bar is 60Pd-40Ag alloy.
