5154A-O Aluminum vs. Annealed SAE-AISI 5160

5154A-O aluminum belongs to the aluminum alloys classification, while annealed SAE-AISI 5160 belongs to the iron alloys. 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 5154A-O aluminum and the bottom bar is annealed SAE-AISI 5160.
