5050 Aluminum vs. ASTM A369 Grade FP92

5050 aluminum belongs to the aluminum alloys classification, while ASTM A369 grade FP92 belongs to the iron alloys. There are 31 material properties with values for both materials. Properties with values for just one material (2, 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 5050 aluminum and the bottom bar is ASTM A369 grade FP92.
