SAE-AISI H11 Steel vs. 6065 Aluminum

SAE-AISI H11 steel belongs to the iron alloys classification, while 6065 aluminum belongs to the aluminum alloys. There are 23 material properties with values for both materials. Properties with values for just one material (8, 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 SAE-AISI H11 steel and the bottom bar is 6065 aluminum.
