7075 aluminum is a kind of aluminum alloy, while AISI 316 stainless steel is a kind of iron alloy. There are 13 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 dissilar densities. This means that additional care is required when interpreting the data, because some material properties are based on a unit of mass, while others are based on units of area or volume.
