4032 Aluminum vs. EN 1.4823 Stainless Steel

4032 aluminum belongs to the aluminum alloys classification, while EN 1.4823 stainless steel belongs to the iron alloys. There are 29 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 4032 aluminum and the bottom bar is EN 1.4823 stainless steel.
