SAE-AISI M6 Steel vs. Commercially Pure Palladium

SAE-AISI M6 steel belongs to the iron alloys classification, while commercially pure palladium belongs to the otherwise unclassified metals. There are 15 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI M6 steel and the bottom bar is commercially pure palladium.
