Full-hard 60Pd-40Ag Alloy vs. Full-hard Palladium

Both full-hard 60Pd-40Ag alloy and full-hard palladium are otherwise unclassified metals. Both are furnished in the full-hard temper. They have 60% of their average alloy composition in common. There are 18 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is full-hard 60Pd-40Ag alloy and the bottom bar is full-hard palladium.
