AWS E410 vs. EN AC-21000 Aluminum

AWS E410 belongs to the iron alloys classification, while EN AC-21000 aluminum belongs to the aluminum alloys. There are 27 material properties with values for both materials. Properties with values for just one material (4, 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 AWS E410 and the bottom bar is EN AC-21000 aluminum.
