6106 Aluminum vs. Nickel 22

6106 aluminum belongs to the aluminum alloys classification, while nickel 22 belongs to the nickel 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 6106 aluminum and the bottom bar is nickel 22.
