Cold Worked R60901 Alloy vs. Work Hardened ASTM B522 Class II

Both cold worked R60901 alloy and work hardened ASTM B522 class II are otherwise unclassified metals. Both are furnished in the cold worked (strain hardened) condition. There are 18 material properties with values for both materials. Properties with values for just one material (8, 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 cold worked R60901 alloy and the bottom bar is work hardened ASTM B522 class II.
