R60802 Alloy vs. R05255 Alloy

Both R60802 alloy and R05255 alloy are otherwise unclassified metals. Both are furnished in the annealed condition. 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 R60802 alloy and the bottom bar is R05255 alloy.
