K94200 Alloy vs. 2014A Aluminum
K94200 alloy belongs to the iron alloys classification, while 2014A aluminum belongs to the aluminum alloys. There are 22 material properties with values for both materials. Properties with values for just one material (9, 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 K94200 alloy and the bottom bar is 2014A aluminum.
