EN 1.0314 Steel vs. EN AC-21100 Aluminum
EN 1.0314 steel belongs to the iron alloys classification, while EN AC-21100 aluminum belongs to the aluminum 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 EN 1.0314 steel and the bottom bar is EN AC-21100 aluminum.
