1100A Aluminum vs. ASTM A387 Grade 22L Class 1

1100A aluminum belongs to the aluminum alloys classification, while ASTM A387 grade 22L class 1 belongs to the iron alloys. There are 30 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 1100A aluminum and the bottom bar is ASTM A387 grade 22L class 1.
