K93600 Alloy vs. 2018 Aluminum

K93600 alloy belongs to the iron alloys classification, while 2018 aluminum belongs to the aluminum alloys. There are 21 material properties with values for both materials. Properties with values for just one material (11, 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 K93600 alloy and the bottom bar is 2018 aluminum.
